Description

Technical Field

[0001] The present invention relates to the technical field of cleaning supplies, and particularly to a flat mop.

Background Art

[0002] A flat mop is a common cleaning tool, comprising a mop rod and a flat mop head. The mop rod is hinged to the mop head, and a wiping cloth is provided on the bottom surface of the mop head. Currently commercially available flat mops fix the wiping cloth by clamping it. When the wiping cloth is removed, the clamping of the wiping cloth by the mop head is released, and the wiping cloth comes off the mop head. However, currently commercially available mop heads clamp and attach the wiping cloth by horizontally moving the side plates of the mop head. This attachment method has problems such as being difficult to clamp the wiping cloth, and the wiping cloth being likely to come off the mop head during operation, which is time-consuming and laborious.

Summary of the Invention

Problems to be Solved by the Invention

[0003] In view of this, the embodiments of this specification provide a flat mop that can more easily clamp a wiping cloth.

Means for Solving the Problems

[0004] To achieve the above object, the present invention provides the following technical solutions. A flat mop comprising a mop rod assembly and a mop head assembly provided at one end of the mop rod assembly, wherein the mop head assembly includes a mounting housing, a cloth clamping plate for clamping a wiping cloth, and moving members slidably mounted on both sides of the mop head assembly and capable of synchronously expanding outward or folding inward. An inner end of the moving member and an outer end of the cloth clamping plate form a cloth clamping space. When the wiping cloth is clamped, the moving member can expand obliquely downward outward, and after driving the wiping cloth, the moving member contracts obliquely upward inward, and the wiping cloth is clamped. A sliding chamber for the moving member to slide is formed between the mounting housing and the cloth clamping plate. There is a side plate at the lower end of the moving member for cooperating with the cloth clamping plate to clamp the wiping cloth. A guide flange is provided downward on the mounting housing, and an avoidance groove corresponding to the guide flange is provided on the moving member. When replacing the wiping cloth, the moving member expands the side plate outward, the guide flange disengages from the avoidance groove, the guide flange presses the moving member to incline the side plate, making the lower edge of the side plate lower than the cloth clamping plate, and the inner end of the side plate and the outer end of the cloth clamping plate form a cloth clamping space. When the wiping cloth is clamped, the frictional force between the side plate and the wiping cloth increases, and the wiping cloth is driven to contract inward and be clamped.

[0005] Compared with the prior art, the advantages of the present invention are as follows. When the wiping cloth is clamped, the moving member expands the side plate outward, and the guide flange guides the moving member and the side plate to move obliquely downward, making the lower edge of the side plate lower than the cloth clamping plate. The inner end of the side plate and the outer end of the cloth clamping plate form a cloth clamping space, and the edge of the wiping cloth is placed in the cloth clamping space. The moving member drives the side plate to fold inward to realize clamping of the wiping cloth. The guide flange guides the moving member and the side plate to move obliquely downward, so that the volume is larger than the cloth clamping space formed by the horizontal movement of the normal side plate, and more wiping cloths can be clamped. The frictional force between the side plate and the wiping cloth increases, and the clamping of the wiping cloth becomes easier.

[0006] In some embodiments, the mop rod assembly includes a universal joint, a straight rod, and a protective housing sleeved on the lower end of the straight rod. The upper end of the universal joint is hinged to the protective housing, the lower end of the universal joint is hinged to the mounting housing, a first positioning bump for left and right centering positioning is provided at the lower end of the protective housing, and a second positioning bump for front and rear centering positioning is provided at the lower end of the universal joint.

[0007] Compared with the prior art, the advantages of the present invention are as follows. When the first positioning bump positions by centering left and right with respect to the universal joint, during the process of the flat mop moving back and forth, the straight rod does not swing left and right. When most of the second positioning bumps position by centering front and rear with respect to the protective housing, during the process of the flat mop moving left and right, the straight rod does not swing back and forth. The operation process of the flat mop is more stable. Moreover, when clamping the wiping cloth, the moving member can be deployed obliquely downward to the outside, and has a larger volume than the cloth clamping space formed by the horizontal movement of a normal moving member, can clamp more wiping cloths, the frictional force between the moving member and the wiping cloth becomes larger, and it is easier to clamp the wiping cloth.

[0008] In some embodiments, the flexible joint is provided with a first positioning groove that coincides with the first positioning bump. When the flexible joint is provided coaxially with the protection housing, the first positioning bump is received in the first positioning groove. On the upper end surface of the mounting housing, a second positioning groove that coincides with the second positioning bump is provided. When the flexible joint is installed coaxially with the mounting housing, the second positioning bump is received in the second positioning groove. By the above improvement, when the flexible joint is provided coaxially with the protection housing, the first positioning bump is received in the first positioning groove. A second positioning bump is provided at the lower end of the flexible joint. On the upper end surface of the mounting housing, a second positioning groove that coincides with the second positioning bump is provided. When the flexible joint is installed coaxially with the mounting housing, the second positioning bump is received in the second positioning groove. When the first positioning bump centers and positions the flexible joint left and right, during the process of the flat mop moving back and forth to operate, the linear rod does not swing left and right. When most of the second positioning bumps center and position the flexible joint front and back relative to the protection housing, during the process of the flat mop moving left and right to operate, the linear rod does not swing back and forth, and the flat mop is more stable during the operation of the flat mop.

[0009] In some embodiments, the rotating gear is provided with a connecting portion for connecting the mop rod assembly. The mounting housing is provided with a connecting hole for passing the connecting portion. A locking member is provided on the side wall of the connecting portion. A locking groove for penetrating the locking member is provided at the edge of the connecting hole. When the position of the locking member corresponds to the locking groove, the connecting portion penetrates the connecting hole. Rotate the rotating gear so that the locking member disengages from the locking groove and the lower end surface of the locking member abuts against the upper end surface of the mounting housing. By the above improvement, when the locking member disengages from the locking groove and the lower end surface of the locking member abuts against the upper end surface of the mounting housing, the rotating gear is positioned and the downward movement of the rotating gear is prevented.

[0010] In some embodiments, the mop rod assembly is provided with a rotational drive mechanism for connecting the moving member. The rotational drive mechanism includes a rotational gear connected to the mop rod assembly and a rack provided on the side plate, and the rack meshes with the rotational gear. By the above improvement, by controlling the rotational drive mechanism, the rotation of the rotational gear is controlled and the rack is reciprocated to realize the movement of the moving member.

[0011] In some embodiments, the mop rod assembly includes a straight rod, a twist rod, and a connecting member. The twist rod rotates the rotational gear. The twist rod is fitted into the straight rod of the mop rod assembly. The lower end of the twist rod is hingedly connected to the rotational gear by the connecting member. The up-and-down movement of the straight rod of the mop rod assembly rotates the rotational gear. By the above improvement, the up-and-down movement of the straight rod rotates the twist rod, thereby rotating the rotational gear, realizing the opening and closing of the side plate, and being more labor-saving and convenient.

[0012] In some embodiments, the mop rod assembly includes a straight rod and a connecting member. The straight rod is directly hingedly connected to the rotational gear by the connecting member, and the rotational gear is rotated by rotating the straight rod. By the above improvement, the rotation of the straight rod rotates the rotational gear, realizing the opening and closing of the side plate, with simple mechanical transmission, higher fault tolerance rate, and being more convenient and efficient.

[0013] In some embodiments, the moving member is provided with a lateral guide groove and a guide bump that coincides with the lateral guide groove. The guide bumps of adjacent moving members are provided in the lateral guide groove of another moving member. By the above improvement, by providing the guide bump in the lateral guide groove, the movement of adjacent moving members is guided, preventing the deviation of the movement trajectories of adjacent moving members and making the operation of the device more stable.

[0014] In some embodiments, a return groove is provided in the guide bump, the mop head assembly is provided with an elastic member, the mounting housing is provided with a positioning block, the elastic member is provided in the return groove, one end of the elastic member abuts against the inner wall surface of the return groove, and the other end of the elastic member abuts against the wall surface of the positioning block. By the above improvement, when the moving member moves outward, the elastic member is compressed. At this time, it is necessary to continuously work on the linear rod so that the gear does not rotate due to the force generated by the restoring deformation of the elastic member. When the moving member moves inward and continuously works on the linear rod, the cloth clamping plate and the side plate cooperate to not work on the linear rod. Due to the force generated by the restoring deformation of the elastic member, the moving member moves inward to realize the clamping of the wiping cloth. Furthermore, since the force required to overcome the deformation of the elastic member is relatively large, it can be ensured that the wiping cloth does not easily come off from the clamping between the cloth clamping plate and the side plate due to an external force during operation.

[0015] In some embodiments, the positioning block is provided with a first positioning post provided on the wall surface of the positioning block, the guide bump is provided with a second positioning post provided on the inner end surface of the return groove, and both ends of the elastic member are respectively sleeved on the first positioning post and the second positioning post. By the above improvement, in order to prevent the elastic member from moving during the process of compression or restoring deformation, both ends of the elastic member are sleeved on the first positioning post and the second positioning post, and both ends of the elastic member are restricted, so that the elastic member is more stable during operation.

[0016] In some embodiments, first tooth portions are provided on both opposite sides of the cloth clamping plate, second tooth portions that coincide with the first tooth portions are provided on the side plates, and the second tooth portions are provided with protruding portions that protrude downward, and the protruding portions are provided to incline from the inside to the outside. By the above improvement, when the wiping cloth is clamped by the cooperation of the first tooth portion and the second tooth portion, due to the meshing arrangement of the first tooth portion and the second tooth portion, the contact area and frictional force between the first tooth portion, the second tooth portion and the wiping cloth are increased, making it difficult for the wiping cloth to come off from the clamping between the cloth clamping plate and the side plate, resulting in stronger clamping. The protruding portion is provided to incline from the inside to the outside, increasing the contact area between the second tooth portion and the wiping cloth, obtaining a greater clamping force, and facilitating the clamping of the wiping cloth.

Advantages of the Invention

[0017] The present invention provides a flat mop that can more easily hold a wiping cloth. When the wiping cloth is held, the moving member expands the side plates outward, and the guide convex edge guides the moving member and the side plates to move obliquely downward, making the lower edge of the side plate lower than the cloth holding plate. The inner end of the side plate and the outer end of the cloth holding plate form a cloth holding space, and the edge of the wiping cloth is placed in the cloth holding space. The moving member drives the side plates to fold inward to realize the holding of the wiping cloth. The guide convex edge guides the moving member and the side plates to move obliquely downward, so that the volume is larger than that of the cloth holding space formed by the horizontal movement of the normal side plates, and more wiping cloths can be held. The frictional force between the side plates and the wiping cloth increases, making it easier to hold the wiping cloth. By controlling the rotational drive mechanism, the rotation of the rotating gear is controlled and the rack is reciprocated to realize the movement of the moving member. When the moving member moves outward, the elastic member is compressed. At this time, it is necessary to continuously work on the linear rod so that the gear does not rotate due to the force generated by the restoration deformation of the elastic member. The moving member moves inward. In the process of continuously working on the linear rod, the cloth holding plate and the side plates cooperate to not work on the linear rod. Due to the force generated by the restoration deformation of the elastic member, the moving member moves inward to realize the holding of the wiping cloth. Furthermore, since the force required to overcome the deformation of the elastic member is relatively large, it can be ensured that the wiping cloth does not easily come off from the clamping between the cloth holding plate and the side plates due to an external force during operation.When the wiping cloth is clamped by the cooperation of the first tooth part and the second tooth part, due to the meshing arrangement of the first tooth part and the second tooth part, the contact area and frictional force among the first tooth part, the second tooth part and the wiping cloth increase, making it difficult for the wiping cloth to come off from the clamping between the cloth clamping plate and the side plate, strengthening the clamping, the protruding part is provided with an inclination from the inner side to the outer side, increasing the contact area between the second tooth part and the wiping cloth, obtaining a greater clamping force, facilitating the clamping of the wiping cloth. When the first positioning bump centers and positions left and right with respect to the universal joint, during the process that the flat mop moves back and forth, the linear rod does not swing left and right. When most of the second positioning bumps center and position back and forth with respect to the protection housing, during the process that the flat mop moves left and right, the linear rod does not swing back and forth, and the flat mop is more stable during the operation of the flat mop.

However, those skilled in the art can more easily understand other advantages and effects of the present application from the content disclosed in this specification. Of course, the described embodiments are only some embodiments of the present application, not all embodiments. The present application can be implemented or applied through other specific embodiments, and various details in this specification can be modified and changed based on different viewpoints and applications without departing from the spirit of the present application.

All other embodiments obtained by those skilled in the art based on the embodiments of the present application without creative efforts belong to the protection scope of the present application.

[0021] In addition, in the following description, specific details are provided to facilitate the understanding of the embodiments. However, those skilled in the art will understand that these specific details are not necessary for implementation.

[0022] Hereinafter, with reference to the drawings, the technical solutions provided by each embodiment of the present application will be described.

[0023] Example 1: As shown in FIGS. 1 to 11 and FIGS. 13 to 16, in this embodiment, there is a flat mop, which includes a mop rod assembly 1 and a mop head assembly 2 provided at one end of the mop rod assembly 1. On both sides of the mop head assembly 2, moving members 2.2 that can be synchronously deployed outward or folded inward are slidably attached. The mop head assembly 2 includes a mounting housing 2.1 and a cloth clamping plate 2.3 for clamping a wiping cloth. A sliding chamber for the moving member 2.2 to slide is formed between the mounting housing 2.1 and the cloth clamping plate 2.3. At the lower end of the moving member 2.2, there is a side plate 2.4 for cooperating with the cloth clamping plate 2.3 to clamp the wiping cloth. A guide flange 2.1.1 is provided downward on the mounting housing 2.1, and an avoidance groove 2.2.2 corresponding to the guide flange 2.1.1 is provided on the moving member 2.2. When replacing the wiping cloth, the moving member 2.2 expands the side plate 2.4 outward, the guide flange 2.1.1 disengages from the avoidance groove 2.2.2, the guide flange 2.1.1 presses the moving member 2.2 to incline the side plate 2.4, making the lower edge of the side plate 2.4 lower than the cloth clamping plate 2.3, and the inner end of the side plate 2.4 and the outer end of the cloth clamping plate 2.3 form a cloth clamping space. When clamping the wiping cloth, the frictional force between the side plate and the wiping cloth increases, driving the wiping cloth to contract inward and be clamped.

[0024] When clamping the wiping cloth, the moving member 2.2 expands the side plate 2.4 outward, and the guide flange 2.1.1 guides the moving member 2.2 and the side plate 2.4 to move obliquely downward, making the lower edge of the side plate 2.4 lower than the cloth clamping plate 2.3. The inner end of the side plate 2.4 and the outer end of the cloth clamping plate 2.3 form a cloth clamping space. The edge of the wiping cloth is placed in the cloth clamping space. The moving member 2.2 drives the side plate 2.4 to fold inward to realize clamping of the wiping cloth. By guiding the moving member 2.2 and the side plate 2.4 to move obliquely downward, the guide flange 2.1.1 forms a cloth clamping space with a larger volume than that formed by the horizontal movement of the normal side plate 2.4, and can clamp more wiping cloth. The frictional force between the side plate 2.4 and the wiping cloth increases, making it easier to clamp the wiping cloth.

[0025] In some embodiments, as shown in FIGS. 12 to 16, the mop rod assembly 1 includes a universal joint 1.3, a straight rod 1.1, and a protective housing 1.4 sleeved on the lower end of the straight rod 1.1. The upper end of the universal joint 1.3 is hinged to the protective housing 1.4, and the lower end of the universal joint 1.3 is hinged to the mounting housing 2.1. A first positioning bump 1.4.1 is provided at the lower end of the protective housing 1.4, and a first positioning groove 1.7 that coincides with the first positioning bump 1.4.1 is provided on the universal joint 1.3. When the universal joint 1.3 is provided coaxially with the protective housing 1.4, the first positioning bump 1.4.1 is received in the first positioning groove 1.7. A second positioning bump 1.8 is provided at the lower end of the universal joint 1.3, and a second positioning groove 2.1.4 that coincides with the second positioning bump 1.8 is provided on the upper end surface of the mounting housing 2.1. When the universal joint 1.3 is installed coaxially with the mounting housing 2.1, the second positioning bump 1.8 is received in the second positioning groove 2.1.4. When the universal joint 1.3 is provided coaxially with the protective housing 1.4, the first positioning bump 1.4.1 is received in the first positioning groove 1.7. A second positioning bump 1.8 is provided at the lower end of the universal joint 1.3, and a second positioning groove 2.1.4 that coincides with the second positioning bump 1.8 is provided on the upper end surface of the mounting housing 2.1. When the universal joint 1.3 is installed coaxially with the mounting housing 2.1, the second positioning bump 1.8 is received in the second positioning groove 2.1.4. During the operation of the flat mop, the sway of the straight rod 1.1 is prevented, and the flat mop is more stable.

[0026] In some embodiments, as shown in FIG. 10, the mop rod assembly 1 includes a rotational drive mechanism for connecting a moving member 2.2. The rotational drive mechanism includes a rotational gear 1.2 connected to the mop rod assembly 1 and a rack 2.2.1 provided on a side plate 2.4. The rack 2.2.1 meshes with the rotational gear 1.2. By controlling the rotational drive mechanism, the rotation of the rotational gear 1.2 is controlled and the rack 2.2.1 is reciprocated to realize the movement of the moving member 2.2.

[0027] In some embodiments, as shown in FIG. 10, the mop rod assembly 1 includes a straight rod 1.1, a twist rod 1.5, and a connecting member 1.6. The twist rod 1.5 rotates the rotating gear 1.2. The twist rod 1.5 is fitted into the straight rod 1.1 of the mop rod assembly 1. The lower end of the twist rod 1.5 is hinge-connected to the rotating gear 1.2 by the connecting member 1.6. The vertical movement of the straight rod 1.1 of the mop rod assembly 1 rotates the rotating gear 1.2. The vertical movement of the straight rod 1.1 rotates the twist rod 1.5, thereby rotating the rotating gear 1.2, realizing the opening and closing of the side plate 2.4, and making it more labor-saving and convenient.

[0028] In some embodiments, as shown in FIGS. 1-2, the mop rod assembly 1 includes a universal joint 1.3 and a protective housing 1.4. The mounting housing 2.1 includes two lug plates 2.1.3 provided opposite to the upper end surface of the mounting housing 2.1. The lower end of the universal joint 1.3 is hinge-connected to the lug plate 2.1.3. The upper end of the universal joint 1.3 is hinge-connected to the protective housing 1.4. And the straight rod 1.1 is inserted into the protective housing 1.4. The central axis about which the universal joint 1.3 is hinge-connected to the lug plate 2.1.3 and the central axis about which the universal joint 1.3 is hinge-connected to the protective housing 1.4 are perpendicular to each other. The protective housing 1.4 is provided to protect the straight rod 1.1, and the straight rod 1.1 is rotatable within the protective housing 1.4 to control the movement of the rotating gear 1.2. Since the central axis about which the universal joint 1.3 is hinge-connected to the lug plate 2.1.3 and the central axis about which the universal joint 1.3 is hinge-connected to the protective housing 1.4 are perpendicular to each other, the straight rod 1.1 can rotate along the direction of the central axis about which the universal joint 1.3 is hinge-connected to the lug plate 2.1.3, and at the same time, the straight rod 1.1 can rotate along the direction of the central axis about which the universal joint 1.3 is hinge-connected to the protective housing 1.4. Thereby, the mop can be applied to various use scenarios and storage scenarios.

[0029] In some embodiments, as shown in FIGS. 12 to 16, the rotating gear 1.2 is provided with a connecting portion 1.2.1 for connecting the mop rod assembly 1. The mounting housing 2.1 is provided with a connecting hole 2.1.5 for passing the connecting portion 1.2.1. A locking member 1.2.2 is provided on the side wall of the connecting portion 1.2.1. A locking groove 2.1.6 for passing the locking member 1.2.2 is provided at the edge of the connecting hole 2.1.5. When the position of the locking member 1.2.2 corresponds to the locking groove 2.1.6, the connecting portion 1.2.1 penetrates the connecting hole 2.1.5, the locking member 1.2.2 disengages from the locking groove 2.1.6, and the rotating gear 1.2 is rotated so that the lower end surface of the locking member 1.2.2 abuts against the upper end surface of the mounting housing 2.1. When the locking member 1.2.2 disengages from the locking groove 2.1.6 and the lower end surface of the locking member 1.2.2 abuts against the upper end surface of the mounting housing 2.1, the rotating gear 1.2 is positioned and downward movement of the rotating gear 1.2 is prevented. The moving member 2.2 is provided with a lateral guiding groove 2.2.3 and a guiding bump 2.2.4 that coincides with the lateral guiding groove 2.2.3. The guiding bumps 2.2.4 of adjacent moving members 2.2 are provided in the lateral guiding grooves 2.2.3 of other moving members 2.2. By providing the guiding bump 2.2.4 in the lateral guiding groove 2.2.3, the movement of adjacent moving members 2.2 is guided, deviation of the movement trajectories of adjacent moving members 2.2 is prevented, and the operation of the device is stabilized.

[0030] In some embodiments, as shown in FIGS. 3 to 6, the moving member 2.2 is provided with a lateral guiding groove 2.2.3 and a guiding bump 2.2.4 that coincides with the lateral guiding groove 2.2.3. The guiding bumps 2.2.4 of adjacent moving members 2.2 are provided in the lateral guiding grooves 2.2.3 of other moving members 2.2. By providing the guiding bump 2.2.4 in the lateral guiding groove 2.2.3, the movement of adjacent moving members 2.2 is guided, deviation of the movement trajectories of adjacent moving members 2.2 is prevented, and the operation of the device is made more stable.

[0031] In some embodiments, as shown in FIGS. 3 to 6, a return groove 2.2.4.1 is provided in the guide bump 2.2.4, the mop head assembly 2 is provided with an elastic member 2.5, the mounting housing 2.1 is provided with a positioning block 2.1.2, the elastic member 2.5 is provided in the return groove 2.2.4.1, one end of the elastic member 2.5 abuts against the inner wall surface of the return groove 2.2.4.1, and the other end of the elastic member 2.5 abuts against the wall surface of the positioning block 2.1.2. When the moving member 2.2 moves outward, the elastic member 2.5 is compressed. At this time, it is necessary to continuously operate on the linear rod 1.1 so that the gear does not rotate due to the force generated by the restoring deformation of the elastic member 2.5. When the moving member 2.2 moves inward and continuously operates on the linear rod 1.1, the cloth clamping plate 2.3 and the side plate 2.4 cooperate to not operate on the linear rod 1.1. Due to the force generated by the restoring deformation of the elastic member 2.5, the moving member 2.2 moves inward to realize the clamping of the wiping cloth. Furthermore, since the force required to overcome the deformation of the elastic member 2.5 is relatively large, it can be ensured that the wiping cloth is not easily disengaged from the clamping between the cloth clamping plate 2.3 and the side plate 2.4 by an external force during operation.

[0032] In some embodiments, as shown in FIGS. 3 to 6, the positioning block 2.1.2 is provided with a first positioning post 2.1.2.1 provided on the wall surface of the positioning block 2.1.2, the guide bump 2.2.4 is provided with a second positioning post 2.2.4.2 provided on the inner end surface of the return groove 2.2.4.1, and both ends of the elastic member 2.5 are sleeved on the first positioning post 2.1.2.1 and the second positioning post 2.2.4.2 respectively. In order to prevent the elastic member 2.5 from moving during the process of compression or restoring deformation, both ends of the elastic member 2.5 are sleeved on the first positioning post 2.1.2.1 and the second positioning post 2.2.4.2. Both ends of the elastic member 2.5 are restricted, and the elastic member 2.5 is more stable during operation.

[0033] In some embodiments, as shown in FIGS. 7 to 9, first tooth portions 2.3.1 are provided on both opposite sides of the cloth clamping plate 2.3, and second tooth portions 2.4.1 that coincide with the first tooth portions 2.3.1 are provided on the side plates 2.4. Moreover, the second tooth portions 2.4.1 are provided with protruding portions 2.4.1.1 that protrude downward, and the protruding portions 2.4.1.1 are provided to be inclined from the inside to the outside. By means of the above improvement, when the wiping cloth is clamped by the cooperation of the first tooth portions 2.3.1 and the second tooth portions 2.4.1, due to the meshing arrangement of the first tooth portions 2.3.1 and the second tooth portions 2.4.1, the contact area and the frictional force between the first tooth portions 2.3.1, the second tooth portions 2.4.1 and the wiping cloth are increased, making it difficult for the wiping cloth to come off from the clamping between the cloth clamping plate 2.3 and the side plates 2.4, and the clamping becomes stronger. The protruding portions 2.4.1.1 are provided to be inclined from the inside to the outside, increasing the contact area between the second tooth portions 2.4.1 and the wiping cloth, obtaining a greater clamping force, and facilitating the clamping of the wiping cloth.

[0034] In some embodiments, as shown in FIGS. 7 to 9, the side plate 2.4 is provided with two mounting strips 2.4.2 provided along the length direction of the side plate 2.4 on the upper end surface of the side plate 2.4. There is a gap between the two mounting strips 2.4.2. A plurality of positioning bumps 2.4.2.1 are provided on both side surfaces of the mounting strip 2.4.2. An installation chamber 2.2.5 for accommodating the mounting strip 2.4.2 is provided on the lower end surface of the moving member 2.2. A positioning strip 2.2.5.2 is provided in the installation chamber 2.2.5. The positioning strip 2.2.5.2 is provided in the gap between the two mounting strips 2.4.2. The positioning strip 2.2.5.2 is provided with a mounting opening 2.2.5.2.1 that cooperates with the positioning bumps 2.4.2.1 between the two mounting strips 2.4.2. The wall surface of the mounting opening 2.2.5.2.1 abuts against the bottom wall surface of the positioning bumps 2.4.2.1 between the two mounting strips 2.4.2. The outer wall surfaces of the positioning bumps 2.4.2.1 outside the two mounting strips 2.4.2 abut against the inner wall surface of the installation chamber 2.2.5. When the side plate 2.4 is attached to the moving member 2.2, by pressing the side plate 2.4, the mounting strip 2.4.2 can be provided in the installation chamber 2.2.5, and the positioning strip 2.2.5.2 can be provided between the two mounting strips 2.4.2 to achieve positioning.
