Referring to fig. 1 to 5, the fixing portion 20 of the suspension device 100 includes a sleeve portion 21, two connecting portions 22 extending vertically upward from both sides of the sleeve portion 21 to be connected to the body portion 10, and an intermediate portion 25 located between the two connecting portions 22 and on a side of the body portion 10 close to the sleeve portion 21. In the present embodiment, the intermediate portion 25 is connected between the two connecting portions 22, but in other embodiments, the intermediate portion 25 may be connected to any position of the suspension device 100, but needs to be provided at a position on one side of the sleeve portion 21 and between the two connecting portions 22 in order to achieve a reinforcing support function of the rotation stop structure of the rotation stop tool attachment 200 described below in the present embodiment. The sleeve portion 21 has a cylindrical structure with a hollow interior and an annular cross section. Specifically, the sleeve portion 21 has a first side wall 211, a second side wall 212, and third and

fourth side walls

213 and 214 connected to the first and

second side walls

In other embodiments, the sleeve portion 21 may have other cross-sectional shapes, and in a preferred embodiment, the sleeve portion 21 may have a pair of side walls 211 disposed opposite to each other, and the number of the side walls 211 is at least one pair, so as to match the side surfaces of the tool attachment 200 where the slots 202 are disposed, which is beneficial to the rotation stopping effect of the tool attachment 200. It is to be understood that other technical features of the second embodiment of the present invention are substantially identical to those of the first embodiment, and only the first embodiment will be described in detail below.

The intermediate portion 25 of the first embodiment herein is an arcuate structure having first and

second connection plates

251, 252 on either side and an arcuate plate 253 centrally located connecting the first and

second connection plates

251, 252. The first and second connecting

plates

251 and 252 are angled toward each other to provide an offset space on the inside of the arcuate plate 253 to clear and receive the end of the tool attachment 200. The intermediate portion 25 includes a rib 254 formed to protrude inward from an inner wall surface thereof, and a connecting strip 255 extending in a direction toward the sleeve portion 21 along the rib 254 and connecting an outer side wall of the sleeve portion 21, and the connecting strip 255 is integrally formed with the rib 254. The connecting strips 255 have a thickness inwardly larger than the wall thickness of the sleeve portion 21, and the connecting strips 255 may protrude inwardly to engage with the rotation stopping tool attachment 200, and the connecting strips 255 may connect with the sleeve portion 21 and protrude inwardly from the outer wall of the sleeve portion 21, and may have a thicker and more stable rotation stopping structure. The tool attachment 200 is accommodated in the sleeve portion 21, the U-shaped cross-sectional grooves 202 on both sides of the tool attachment 200 correspond to the first and

second side walls

211, 212, respectively, and the ribs 254 engage with the grooves 202 to achieve locking. Specifically, when the tool attachment 200 is inserted in the axial direction of the sleeve portion 21, the rib 254 is elastically deformed to enter the groove 202 and engage with the groove 202, preventing the tool attachment 200 from rotating in the sleeve portion 21, and achieving a rotation stop function.

Two accommodating spaces 23 located on both sides of the connecting bar 255 are formed between the sleeve portion 21 and the intermediate portion 25, and the connecting portion 22 has elastic hooks 24 extending into the accommodating spaces 23. The working attachment 200 is provided with slots 201 at both sides thereof, and when the tool attachment 200 is inserted, the elastic hooks 24 are elastically deformed to enter the slots 201 and engage with the slots 201 to fixedly receive the tool attachment 200 in the sleeve portion 21, thereby preventing the tool attachment 200 from being detached. Further, each connecting portion 22 includes a first extending portion 221 and a second extending portion 222. The first extension part 221 is formed by extending obliquely upwards from the side wall of the sleeve part 21, the sleeve part 21 is located below the first extension part 221, the second extension part 222 is formed by extending vertically upwards from the top of the first extension part 221 and is connected with the main body 10, and the second extension part 222 extends inwards to form the elastic hook 24 facing the inner edge of the accommodating space 23, as shown in fig. 4. The elastic hook 24 is a cantilever structure extending linearly, has good elasticity, and has a large elastic space along the axial direction of the sleeve portion 21 after being stressed, thereby facilitating the insertion and fixation of the tool accessory 200. In the present embodiment, the extension of the sleeve portion 21 along the axial direction thereof does not exceed the first connection portion 22, the elastic hook 24 is elastically deformed toward the direction of the sleeve portion 21, that is, the axial direction, until the convex corner 2211 of the first extension portion 221 abuts, the convex corner 2211 is located between the sleeve portion 21 and the elastic hook 24, and the convex corner 2211 is provided with a convex corner structure, so that the elastic hook 24 can be prevented from being excessively deformed by the tool accessory 200 in the axial direction of the sleeve portion 21, and the elastic hook 24 can be prevented from being failed.

Specifically, the elastic hook 24 is made of PP material and has strong flexibility and elasticity, a triangular groove 242 is disposed at a corner of the elastic hook 24, the convex angle 2211 of the first extension portion 221 is a triangular protrusion, and a hook head 241 is disposed at an outer side of the groove 242 (at a tail end of the elastic hook 24) of the elastic hook 24. When the tool attachment 200 is accommodated in the sleeve portion 21, the elastic hooks 24 interact with the slots 201 to fixedly accommodate the tool attachment 200 in the sleeve portion 21, so as to prevent the tool attachment 200 from being disengaged or rotating in the sleeve portion 21; more specifically, when the tool attachment 200 is inserted into the through slot 215 along the axial direction of the sleeve portion 21, the top surface of the tool attachment 200 abuts the hook 241 to force the elastic catch 24 to rotate upward to deform elastically to let the tool attachment 200 pass through until the elastic catch 24 enters the slot 201 and is restored under the action of elasticity; after the tool attachment 200 is inserted, the elastic hook 24 enters the slot 201 and then recovers, and when the tool attachment 200 is vertically placed without external force, the tool attachment falls downward under the gravity, and the upper edge of the slot 201 can be propped upward to prevent the tool attachment from falling.

The upper top corner of the elastic hook 24 is forced by the tool attachment 200 to move downward, and as shown in fig. 2, the elastic hook 24 is driven to elastically deform downward, and the convex angle 2211 of the first extension 221 can prop against the groove 242 of the elastic hook 24 to prevent further deformation, so as to prevent the tool attachment 200 from separating downward from the sleeve portion 21. Even if the tool accessory 200 is pulled out, the corner of the first extending portion 221 can be locked with the groove 242 of the elastic hook 24, so as to prevent the tool accessory 200 from falling off easily. The second embodiment of the present invention has technical features and technical effects consistent therewith.

Referring to fig. 7-10, a third embodiment of the suspension apparatus 300 of the present disclosure, which has substantially the same structural features as the suspension apparatus 100 of the first embodiment, will be described in detail with reference to the differences. The sleeve portion 31 of the suspension device 300 extends beyond the first extension 321 in the axial direction thereof, i.e., above the first extension 321, and the elastic hook 34 is elastically deformable downward to abut against the tip end of the sleeve portion 31. The elastic hook 34 includes an arc portion 341 extending from the inner edge of the second extending portion 322, a linear portion 342 extending from the arc portion 341, and a protrusion 343 protruding downward from the linear portion, wherein the protrusion 343 extends into the sleeve portion 31. Specifically, when the tool attachment 200 is inserted into the sleeve portion 31, the protrusion 343 of the top surface of the tool attachment 200 pushes the elastic hook 34 to rotate upward to deform elastically so as to allow the tool attachment 200 to pass through until the elastic hook 34 enters the slot 201 and recovers under the action of elasticity, where the arc portion 341 is provided to enhance the elastic recovery force of the elastic hook 34; referring to fig. 9, after the tool attachment 200 is inserted in the axial direction of the sleeve portion 31, under the outward pulling force, the upper edge of the slot 201 of the tool attachment can abut against the linear portion 342 of the elastic hook 34 downward, so that the elastic hook 34 is forced downward to drive the elastic hook 24 to deform elastically downward, and at this time, the top end of the sleeve portion 31 can abut against the linear portion 342 of the elastic hook 34 to prevent further downward deformation, thereby preventing the tool attachment 200 from separating from the sleeve portion 21. The suspension device 400 of the fourth embodiment has the same structural features as the third embodiment, except that the sleeve portion 31 of the third embodiment is identical to the sleeve portion of the first embodiment, i.e., is defined by two planar side walls and two circular arc side walls. The sleeve portion 34 'of the fourth embodiment has a structure similar to that of the second embodiment, that is, the sleeve portion 34' is surrounded by six planar side walls and has a hexagonal cross section as viewed from the bottom up. The suspension devices of the four embodiments herein are provided with ribs 254 which cooperate with the slots 202 of the tool attachment 200 to achieve a better anti-rotation effect.

The utility model discloses in, protruding muscle 254 corresponds the block respectively in fluting 202 and slot 201 of instrument annex 200 with elasticity pothook 24/34, and the block position of protruding muscle 254 and the position that opens and shuts of elasticity pothook 24/34 all are located the top of sleeve portion 21/31 and are located the concentration range basically, and three block point forms the triangle-shaped block position in certain axial range, and the block plane of three block point is close the level, therefore the block effect is more stable, and the effect of splining is better.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
