[0025] The fastening element and the tool described in the present invention will be further explained and illustrated below in conjunction with the drawings and specific embodiments of the specification. However, such explanation and illustration do not constitute an improper limitation on the technical solution of the present invention.

[0026] Figure 1A tool used in daily production and life is shown. In this example, the tool is an electric tool, such as a reciprocating saw.

[0027] When using the tool, the operator is often required to hold the tool. In order to increase the grip friction and improve the user experience, an outer shell sleeve 200 is often sleeved on the periphery of the tool body 100. The outer shell sleeve is usually a soft sleeve, such as a plastic or rubber soft sleeve.

[0028] However, the existing outer shell sleeve often has the problem of unstable fixation during use, especially after the tool has been used for a period of time. As the tool life increases, the outer shell sleeve 200 often becomes loose due to long-term vibration and wear. For example, it slides in the length direction relative to the tool body 100 during use, or rotates relative to the tool body, which leads to unstable operation and greatly affects the user experience.

[0029] To solve this problem, Figure 2 As shown, the utility model provides a fixing element 300 in one embodiment, which can stably fix the outer shell sleeve 200 on the tool body 100, thereby preventing the outer shell sleeve 200 from moving relative to the tool body 100 in the length direction L and preventing the outer shell sleeve 200 from rotating relative to the tool body 100.

[0030] Figure 3 A schematic diagram of the three-dimensional structure of the fastening element 300 described in the utility model in one embodiment is shown.

[0031] Figure 4 The radial cross-sectional view shows the installation state of the fastening element of the present invention on a tool in one embodiment.

[0032] like Figure 3 and Figure 4 As shown, in one embodiment, the fixing element 300 is provided with a first stop end face 301 and a second stop end face 302 arranged opposite to the first stop end face in the length direction of the tool housing sleeve, and the first stop end face 301 and the second stop end face 302 both extend from a first position P1 corresponding to the tool housing sleeve to a second position P2 corresponding to the tool body, as shown in FIG. Figure 2 and Figure 4 As shown, when the fixing element is installed between the tool housing sleeve 200 and the tool body 100, the first stop end face 301 and the second stop end face 302 cooperate with the tool housing sleeve 200 at the first position P1, and the first stop end face 301 and the second stop end face 302 cooperate with the tool body 100 at the second position P2, so as to prevent the housing sleeve 200 from moving relative to the tool body 100 in the length direction L ( Figure 4Movement in the direction perpendicular to the paper surface).

[0033] It should be noted that, in the present invention, the first position P1 and the second position P2 can be understood as corresponding to the positions of the tool housing sleeve 200 and the tool body 100 in the height direction, respectively.

[0034] In some embodiments, the tool body more specifically refers to a fixedly disposed component within a tool housing, such as a gear box in one specific example.

[0035] In addition, continue to read Figure 3 and Figure 4 The fixing element is provided with a third stop end face 303 and a fourth stop end face 304 arranged opposite to the third stop end face in the width direction of the tool housing sleeve. The third stop end face 303 and the fourth stop end face also extend from a first position P1 corresponding to the tool housing sleeve to a second position P2 corresponding to the tool body. Figure 4 As shown, when the fixing element is installed between the tool housing sleeve 200 and the tool body 100, the third stop end face 303 and the fourth stop end face 304 cooperate with the tool housing sleeve 200 at the first position P1, and the third stop end face 303 and the fourth stop end face 304 cooperate with the tool body 100 at the second position P2, so as to prevent the housing sleeve 200 from moving relative to the tool body 100 in the length direction L ( Figure 4 The outer shell sleeve 200 is prevented from moving in the direction perpendicular to the paper surface) to prevent the outer shell sleeve 200 from rotating around its own axis relative to the tool body 100 in the clockwise direction R1 and the counterclockwise direction R2.

[0036] It should be noted that in various embodiments of the present invention, the first stop end face and the second stop end face are used for limiting in two directions opposite to each other (two directions in the length direction), so the two can be interchanged and switched. Similarly, the third stop end face and the fourth stop end face are also used for limiting in two directions opposite to each other (two directions in the rotation direction or two directions in the width direction), so the two can also be interchanged and switched.

[0037] As a more specific implementation, Figure 3 and Figure 4 Specific forms of the first stop end surface, the second stop end surface, the third stop end surface and the fourth stop end surface in a specific implementation manner are shown.

[0038] like Figure 3 and Figure 4As shown, in some more specific embodiments, the fixing element 300 includes a crossbeam 1 extending in the width direction W of the tool housing sleeve and a support leg 2 extending downward from the crossbeam 1, and two first end faces 11 of the crossbeam 1 arranged oppositely in the length direction L of the housing sleeve are used to form a part of the first stop end face 301 and a part of the second stop end face 302 located at the first position P1. Two second end faces 21 of the support leg 2 arranged oppositely in the length direction L of the housing sleeve are used to form a part of the first stop end face 301 and a part of the second stop end face 302 located at the second position P2. Two third end faces 12 of the crossbeam 1 arranged oppositely in the width direction W of the housing sleeve are used to form a part of the third stop end face 303 and a part of the fourth stop end face 304 located at the first position P1. Two fourth end faces 22 of the support leg 2 arranged oppositely in the width direction W of the housing sleeve are used to form a part of the third stop end face 303 and a part of the fourth stop end face 304 located at the second position P2.

[0039] In some more specific embodiments, Figure 3 and Figure 4 As shown, two legs 2 can be provided. By providing two legs, the fixing element is formed into a bridge structure, which is beneficial to further improve the stability of the fixing element under stress.

[0040] Of course, in some other optional embodiments, only one support foot may be provided. In this case, the two fourth end faces 22 (outer side face and inner side face) of the support foot are respectively used to form a portion of the third stop end face 303 and a portion of the fourth stop end face 304 located at the second position P2.

[0041] In some more specific embodiments, Figure 3 and Figure 4 As shown, the tail end of the leg is provided with a hook-shaped portion 23. The hook-shaped portion is used to cooperate with the tool body 100 and hook on the tool body to prevent the fixing element 300 from being pulled out.

[0042] In some preferred embodiments, the legs 2 can be further configured as flexible legs, such as plastic legs with a certain elasticity, plastic legs, or metal legs with a small thickness. In this way, when an external force is applied to the two legs in the width direction, the two legs can be relatively close to each other. In this state, the legs 2 can be inserted into the leg groove 101 of the tool body 100, and then the external force is removed, and the two legs 2 are relatively opened and reset to a natural state, so that the hook-shaped portion 23 is hooked on the wall next to the leg groove 101, thereby realizing convenient installation of the fixing element. In the same way, convenient removal of the fixing element can also be realized.

[0043] In addition, in some embodiments, Figure 3As shown, the fixing element 300 may further include an auxiliary rib 3 extending downward from the crossbeam 1, and two fifth end faces 31 of the auxiliary rib 3 are arranged opposite to each other in the length direction L of the outer shell sleeve, and are used to form a part of the first stop end face 301 and a part of the second stop end face 302 located at the second position P2. When the auxiliary rib 3 is inserted into the threshold-matched auxiliary rib groove 102 in the tool body 100, for a single auxiliary rib, the two fifth end faces 31 cooperate with the auxiliary rib groove 102 in two directions of the length direction L, which can provide additional limiting force to prevent the outer shell sleeve 200 from moving relative to the tool body 100 in the length direction L thereof.

[0044] Likewise, if Figure 3 and Figure 4 As shown, in some more specific embodiments, the two sixth end faces 32 of the auxiliary rib 3 relatively arranged in the width direction W of the outer shell sleeve can be used to form a fifth stop end face 305 and a sixth stop end face 306 that cooperate with the auxiliary rib groove 102, thereby further helping to prevent the outer shell sleeve 200 from rotating relative to the tool body 100.

[0045] Of course, in some other optional embodiments, the size of the auxiliary rib groove 102 in the width direction W of the outer shell sleeve can be set to be larger than the width of the auxiliary rib 3. In this case, since the sixth end face 32 will not abut against the inner wall of the auxiliary rib groove 102, there is no fifth stop end face and sixth stop end face in this embodiment.

[0046] It should be noted that although Figure 3 and Figure 4 In the illustrated embodiment, two auxiliary ribs 3 are provided, but in other embodiments, one auxiliary rib or more than two auxiliary ribs may also be provided.

[0047] In addition, in some embodiments of the present invention, Figure 3 As shown, the fixing element 300 may further include a reinforcing rib 4 extending downward from the cross beam 1 , and the reinforcing rib may further improve the strength of the bridge-type fixing element.

[0048] It should be noted that the present invention is not limited to Figure 2 As long as the specific implementation form shown can achieve the limit in the length direction and the rotation direction, it is within the protection scope of the present utility model. Figure 2 The bridge-like structure shown can be a sheet-like structure, which extends from a first position P1 to a second position P2 in the height direction, and has two opposite surfaces in the length direction, a first stop end face and a second stop end face, and two opposite surfaces in the width direction, a third stop end face and a fourth stop end face.

[0049] The utility model can effectively avoid the problem of slipping and movement of the outer shell sleeve through the above-mentioned setting scheme, thereby improving the user experience.

[0050] like Figure 2 and Figure 4 As shown, the utility model further provides a tool in another embodiment, which includes a tool body 100 and an outer shell sleeve 200, and further includes a fixing element 300 as described above, wherein the outer shell sleeve 200 is provided with a first receiving groove 201 adapted to the fixing element, and the tool body 100 is provided with a second receiving groove, the fixing element 300 is arranged in the first receiving groove 201 and extends into the second receiving groove, wherein the fixing element 300 abuts against the inner wall of the first receiving groove 201 at the first position P1, and the fixing element 300 abuts against the inner wall of the second receiving groove at the second position P2.

[0051] In some more specific embodiments, when the fastening element has a support leg 2 , the second receiving groove at least includes a support leg groove 101 adapted to the support leg 2 and abutting against it.

[0052] In some more specific embodiments, when the fastening element has an auxiliary rib 3 , the second receiving groove may further include an auxiliary rib groove 102 adapted to and abutting against the auxiliary rib 3 .

[0053] In some embodiments, the tool of the present invention may be a manual tool, and in other embodiments, the tool may be an electric tool.

[0054] Especially when the tool is an electric tool driven by a motor, a large amount of heat is often generated inside the electric tool during operation due to the heavy load of the tool. In order to improve the heat dissipation effect, a cooling air circuit can be provided inside the electric tool.

[0055] like Figure 5 As shown, in some preferred embodiments, when the fixing element 300 has a reinforcing rib 4, a gap P3 is provided between the bottom end of the reinforcing rib 4 and the tool body, especially the internal components of the tool body (such as a gear box), so as to form a channel for the cooling gas path P in the tool body. In other words, the arrangement of the reinforcing rib 4 will not block the cooling gas path P.

[0056] In addition, if Figure 5As shown, in some embodiments, the tool body 100 may be provided with a stopper 110, which may be an original part of the tool body, or a part formed on the tool body, or a part that can be installed on the tool body. Accordingly, the outer shell sleeve 200 is provided with an opening 202 that cooperates with the stopper. In some embodiments, the opening 202 may be an opening that is approximately rectangular. In this way, as Figure 5 As shown, the side wall 1101 of the stopper 110 in the length direction of the tool body and the side wall 2021 of the opening 202 in the length direction of the tool body abut against each other, which can further prevent the outer shell sleeve 200 from moving relative to the tool body 100 in the length direction. At the same time, the stopper 110 can also have a side wall ( Figure 5 The side wall in the width direction is not visible in the figure, and the side wall in the width direction is the same as the side wall in the width direction of the opening 202 ( Figure 5 The outer shell sleeve 200 (not visible in the figure) abuts against each other, which can further prevent the outer shell sleeve 200 from rotating in the circumferential direction relative to the tool body 100.

[0057] It should be noted that when the utility model relates to an electric tool, it does not limit the type of the electric tool. In some more specific embodiments, the electric tool can be an electric reciprocating saw, and in other embodiments, it can also be an electric hammer, an electric screwdriver or other electric tools.

[0058] In addition, the tool housing sleeve 200 involved in the present invention can be a plastic or rubber soft sleeve, or a relatively hard plastic sleeve or metal sleeve.

[0059] When the tool housing sleeve is a plastic or rubber soft sleeve, in order to make the first stop end face and the second stop end face have better supporting force, the housing sleeve can be made of plastic or rubber material with a Shore hardness of 60-80HA.

[0060] In the utility model, the tool body refers to the part that has a clamping relationship with the outer shell sleeve. The fixing element can be installed on the tool body or any hard fixing component in the tool body. It can be installed on the gear box in the tool, or on the motor housing or other similar hard structures.

[0061] It should also be noted that the terms "up", "down", "left" and "right" described in this article are for ease of understanding and are based on Figures 1 to 5 This is an exemplary description of the setting method and direction, which is not intended to limit the present invention.
