DETAILED DESCRIPTION

[0031] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the handheld tool installation mechanism and the handheld tool of the present invention are specifically described below in conjunction with embodiments and drawings.

[0032] <Example>

[0033] Figure 1It is a structural diagram of the handheld tool of the utility model.

[0034] This embodiment provides a handheld tool 100, whose working parts can be replaced. Figure 1 As shown, the handheld tool 100 includes a working component 10 , a body 20 , and a mounting mechanism 30 for detachably mounting the working component 10 on the body 20 .

[0035] Figure 2 It is a cross-sectional view of the installation position of the working parts of the utility model.

[0036] Figure 3 It is a cross-sectional view of the installation mechanism of the utility model.

[0037] like Figure 2 and Figure 3 As shown, the mounting mechanism 30 includes a mounting assembly 40, a sleeve assembly 50 and a connecting body 11. The mounting assembly 40 includes a mounting body 41, a stopper 42 fixedly arranged on the mounting body 41, a locking member 43 movably arranged on the mounting body 41 and an anti-mis-mounting member 44. The sleeve assembly 50 includes a sleeve 51 slidably arranged on the mounting body 41, a reset member 52 pressed between the inner side of the sleeve 51 and the outer side of the mounting body 41 to assist the sleeve 51 in resetting, and a positioning convex ring 53 formed on the inner wall of the sleeve 51. The connecting body 11 is arranged on the working part 10, and is provided with a locking matching portion 12 matched with the locking member 43 and a limiting matching portion 13 matched with the stopper 42. One end of the mounting body 41 is fixedly arranged at the front end of the machine body 20, and the other end is provided with a slot 411 for the connecting body 11 to be inserted, and the connecting body 11 can be detachably mounted on the mounting body 41. The installation of the working component 10 is facilitated by inserting the connecting body 11 into the slot 411 of the installation body 41 .

[0038] Figure 4 It is a structural diagram of the sliding sleeve of the utility model.

[0039] Figure 5 It is a cross-sectional view of the sliding sleeve of the utility model.

[0040] like Figure 3-Figure 5As shown, the sliding sleeve 51 is slidably mounted on the outer periphery of the installation body 41, and a retaining ring 45 is mounted on the outer side of the installation body 41 corresponding to the retaining convex ring 53. The retaining ring 45 and the retaining convex ring 53 cooperate with each other to form a front end limit for the sliding of the sliding sleeve 51 (the "front end" here indicates that the area where the working parts are located is the front, and the area where the body is located is the rear). A sliding sleeve limiter 54 is also embedded in the outer periphery of the installation body 41, and a sliding sleeve limiter groove 55 is opened on the inner side wall of the sliding sleeve 51 along the axial direction. The sliding sleeve limiter groove 55 and the sliding sleeve limiter 54 cooperate with each other to form a rear end limit for the sliding of the sliding sleeve 51. The structural setting of the front end limit and the rear end limit can ensure that the sliding sleeve 51 can always remain on the outer periphery of the installation body 41 to prevent it from detaching from the installation body 41 during the sliding process. As shown in the figure, in this embodiment, the sliding sleeve stopper 54 is a steel ball, and the front end of the sliding sleeve stopper groove 55 is provided with a blocking surface 551 for clamping on the surface of the steel ball, and the sliding sleeve stopper 54 and the sliding sleeve stopper groove 55 are provided with two groups, and are symmetrically distributed on both sides of the installation body 41. The sliding sleeve 51 is provided with a sliding stopper 56 that cooperates with the locking member 43, and the sliding stopper 56 is integrally formed on the inner wall of the sliding sleeve 51. An annular inclined surface 561 and an annular plane 562 are respectively formed on both sides of the sliding stopper 56, and a spring installation surface 412 is formed on the outer side of the installation body 41. The reset member 52 is a reset spring, and the reset spring is pressed between the annular plane 562 and the spring installation surface 412 to assist the reset of the sliding sleeve 51.

[0041] Figure 6 It is a structural diagram of the installation assembly of the utility model.

[0042] Figure 7 It is a cross-sectional view of the installation assembly of the utility model in the axial direction.

[0043] like Figure 6 and Figure 7 As shown, the mounting body 41 is provided with a first mounting hole 413, a second mounting hole 414 and a third mounting hole 415 for mounting the locking member 43, the limiting member 42 and the anti-misinstallation member 44. The centers of the first mounting hole 413, the second mounting hole 414 and the third mounting hole 415 are almost located on the same circumference, and the sliding limiting portion 56 can cover the outer circumference of the first mounting hole 413, the second mounting hole 414 and the third mounting hole 415, so as to limit the internal locking member 43.

[0044] The number of locking members 43 and limiting members 42 is the same, and each locking member 43 corresponds to each limiting member 42 to form a group of axial limiting components to jointly limit the circumferential rotation of the connecting body on the installation body. The anti-mistaken installation member 44 is arranged close to the locking member 43, and an anti-mistaken installation member 44 slightly smaller than the locking member 43 is arranged in front of the rotation trajectory of each locking member 43, which is used to prevent the user from making misoperations during installation and has a prompting effect. In this embodiment, the locking member 43 and the anti-mistaken installation member 44 are both steel balls, and the limiting member 42 is a limiting pin, and three of them are arranged. Each locking member 43, the anti-mistaken installation member 44 and the limiting member 42 are a group, and the three groups are evenly arranged on the installation body 41, wherein the locking member 43 is a locking steel ball, and the anti-mistaken installation member 44 is an anti-mistaken steel ball, and the diameter of the locking steel ball is greater than the diameter of the anti-mistaken steel ball. In this embodiment, the diameter of the locking steel ball is 6mm, and the diameter of the anti-mistaken steel ball is 5.5mm. The locking steel ball and the anti-misinstallation steel ball are respectively rotatably disposed in the first mounting hole 413 and the third mounting hole 415 , and the limiting pin is interference-fitted with the second mounting hole 414 , so that the limiting pin is fixed on the mounting body 41 .

[0045] Figure 8 It is a front view of the slot direction of the installation component of the utility model.

[0046] Fig. 9 It is a radial cross-sectional view of the installation assembly of the utility model.

[0047] In addition, at least one set of clamping parts 416 is provided on the inner wall of the slot 411 of the mounting body 41. In this embodiment, three sets of clamping parts 416 are evenly arranged on the inner wall of the slot 411. A first spacing area 417 (i.e., Figure 6-Figure 8 The smooth inner wall of the middle slot 411), and each group of the clamping parts 416 is composed of a plurality of clamping grooves arranged along the circumferential direction and parallel to each other.

[0048] Fig.10 It is a structural diagram of the connecting body of the utility model.

[0049] Correspondingly, such as Fig.10 As shown, at least one group of snap-fitting parts 14 is provided on the outer surface of the connecting body 11. In this embodiment, three groups of snap-fitting parts 14 are evenly arranged on the outer surface of the connecting body 11, and a second spacing area 15 (i.e., Fig.10 The outer wall of the connecting body 11 is smooth), and each set of the snap-fitting parts 14 is composed of a plurality of clip strips arranged along the circumferential direction and parallel to each other, and the clip strips can be embedded in the clip groove. Figure 2As shown, when the clamping strip is embedded in the clamping slot, the axial movement of the connecting body 11 and the mounting body 41 is restricted, that is, the connecting body 11 will not be separated from the mounting body 41 along the axial direction; when the clamping strip is aligned with the first spacing area, and the clamping slot is aligned with the second spacing area, the connecting body 11 can move axially relative to the mounting body 41. During installation, the clamping fitting portion 14 of the connecting body 11 is first inserted along the first spacing area 417 on the slot 411, and then the connecting body 11 is rotated so that the clamping fitting portion 14 is embedded between the clamping portions 416. The clamping portions and the clamping fitting portions arranged along the circumferential direction can also increase the load or offset the axial force on the working parts during operation, so as to protect the working parts or the connecting body from damage and extend the service life of the structure.

[0050] The width of the first spacer 417 is set to be greater than or equal to the width of the card slot, and the width of the second spacer 15 is set to be greater than or equal to the width of the card strip to ensure that the card strip can be completely separated from the card slot when it is facing the first spacer 417, so that the connecting body can be pulled out.

[0051] Fig.11 It is a cross-sectional view of the installation mechanism of the utility model when the working parts are installed on the machine body.

[0052] like Fig.10 As shown, the locking fitting part 12 is a locking groove provided on the outer peripheral surface of the end of the connecting body, and the locking groove is a concave structure with a low center and high sides; the limiting fitting part 13 is a limiting protrusion formed on the outer peripheral surface of the end of the connecting body, and a blocking surface 131 that can abut against the limiting member 42 is provided on one side of the limiting protrusion. A group of locking grooves and limiting protrusions are provided at the end of each group of snap-fit ​​fitting parts 14.

[0053] When the connection body 11 is rotated in the slot 411 until the limiting member 42 abuts against the limiting protrusion, the connection body 11 cannot be rotated further due to the blocking surface of the side of the limiting protrusion (such as Fig.11 At the same time, the locking member 43 also matches with the locking fitting portion. When the sliding limit portion 56 on the sliding sleeve 51 is located outside the locking member 43, the locking member 43 is locked between the locking fitting portion and the sliding limit portion 56. Combined with the limit on the limit member, the rotation of the connecting body 11 in the circumferential direction is restricted.

[0054] Fig.12 It is a structural diagram of another implementation method of the working part of the utility model.

[0055] The working part 10 of this embodiment can be as follows Figure 1 The structure shown can also be Fig.12The structure shown only needs to be provided with a connecting body 11 and can be installed on the machine body by replacing the installation assembly for use.

[0056] The working parts of this embodiment are installed as follows:

[0057] First, apply force to the sliding sleeve 51 to slide the sliding sleeve 51 along the direction of the body 20, so that the sliding limit portion 56 leaves the position corresponding to the locking piece 43, and then the snap-fitting portion 14 of the connecting body 11 is inserted along the first spacing area 417 on the slot 411, and then the connecting body 11 is rotated. During the rotation process, since the sliding limit portion 56 leaves the locking piece 43 and the anti-misinstallation piece 44, the anti-misinstallation piece 44 and the locking piece 43 can roll along the outer periphery of the end of the connecting body 11 until the limit portion 42 abuts against the limit protrusion. Under the obstruction of the blocking surface on the side of the limit protrusion, the connecting body 11 will no longer be able to continue to rotate, and at this time the locking piece 43 is also just stuck in the locking fitting portion 12, and the snap-fitting portion 416 and the snap-fitting portion 14 are also embedded with each other. Then, the force applied to the sliding sleeve 51 is removed, and the sliding sleeve 51 is reset along the direction of the working component 10 under the drive of the reset member 52, and at the same time, the sliding limiter 56 is also moved to the position corresponding to the locking member 43 and the anti-misinstallation member 44, and is set against the outside of the locking member 43, so that the locking member 43 is locked between the connecting body 11 and the sliding limiter 56, and the installation of the connecting body 11 is completed. In short, in this embodiment, it is only necessary to slide the sliding sleeve 51 first, then insert the connecting body, and then rotate the connecting body, and finally release the sliding sleeve 51 to automatically reset it to complete the quick installation, which is very convenient and quick.

[0058] The working parts of this embodiment are disassembled as follows:

[0059] First, force is applied to the sliding sleeve 51 to slide the sliding sleeve 51 along the direction of the machine body 20, so that the sliding limit portion 56 leaves the position corresponding to the locking member 43, and then the connecting body 11 can be rotated. When the clamping portion 416 is rotated to separate from the clamping fitting portion 14, the connecting body 11 can be directly pulled out along the axial direction to complete the disassembly. In short, in this embodiment, it is only necessary to slide the sliding sleeve 51 first, then rotate the connecting body, and then pull out the connecting body to complete the quick disassembly.

[0060] The above embodiments are only used to illustrate the specific implementation of the utility model, and the utility model is not limited to the description scope of the above embodiments. For example, in the above embodiments, the clamping part 416 in the installation body 41, the first spacing area 417, and the clamping fitting part 14 and the second spacing area 15 on the connecting body 11 are all provided with three groups, and the corresponding limiter 42, the locking part 43 and the anti-misinstallation part 44 are also arranged in three groups. In actual situations, they can also be arranged in only one group, two groups or more groups, and it is only necessary to ensure that the clamping part 416 can slide smoothly with the second spacing area 15 or the clamping fitting part 14 and the first spacing area 417, so that the rapid movement of the connecting body 11 in the axial direction can be ensured, thereby realizing rapid disassembly and assembly.
