[0029] like Figures 1-3 As shown, this embodiment is achieved through the following technical solution: the handle body includes: a handle 1 and an insertion part 2 for inserting instruments.

[0030] The insertion part 2 is hollowed and arranged with a clearance slot 201 and a cantilever-shaped elastic sheet 3, one end of the elastic sheet 3 is connected with the insertion part 2, and the other end of the elastic sheet 3 is elastically movable in the clearance slot 201.

[0031] The insertion part 2 is provided with a limiting pin 4 penetrating the side surface of the insertion part 2 for limiting the downstroke of the elastic sheet 3.

[0032] Specifically, the radial profile of the handle body is stepped and shrinks from the handle part 1 to the insertion part 2, as shown in the figure. Figure 1 Preferably, in the embodiment, the insertion part 2 is a quadrangular body.

[0033] Specifically, the limiting pin 4 is arranged in the clearance slot 201, the limiting pin 4 is arranged to the inner side of the elastic sheet 3, and the elastic sheet 3 can be pressed and abutted on the limiting pin 4. The limiting pin 4 limits the movement range of the elastic sheet 3 in the clearance slot 201, and prevents the elastic sheet 3 from losing elasticity after being pressed by a large force.

[0034] Specifically, the elastic sheet 3 comprises a main body 302, one end of the main body 302 is connected with the insertion part 2, the outer side of the main body 302 is provided with a boss 301 for pressing the elastic sheet 3, and the outer side of the main body 302 is provided with a stopper 303. In the embodiment, the stopper 303 is in a slope shape, and the slope of the stopper 303 faces away from the handle part 1, as shown in the figure. Figure 2 Figure 3 In the normal state without external force, the side of the main body 302 facing away from the clearance slot 201 is in the same plane with the outer wall of the insertion part 2, as shown in the figure. Figure 2

[0035] Specifically, the boss 301 is provided with an anti-skid line 3011.

[0036] Specifically, the handle part 1 is internally provided with a chamber 103, and the side surface of the handle part 1 is provided with a plurality of through holes 101 penetrating the chamber 103; one end of the chamber 103 penetrates the end surface of the handle part 1 to form an opening, as shown in the figure. The handle part 1 is hollowed by arranging the through holes 101 and the chamber 103, thereby reducing the weight of the handle and making the handle feel more light and convenient. Figure 3 The outer wall of the handle part 1 is uniformly provided with a plurality of anti-skid grooves 102.

[0037] Specifically, one end of the handle part 1 is further provided with a sealing cap 5.

[0038] Specifically, the sealing cap 5 is clamped to the opening of the chamber 103.

[0039] The specific use principle of the utility model is as follows:

[0040]

[0041] ​​​In use, the handle 1 is manually held, the insertion part 2 is inserted into the corresponding insertion slot of the instrument, when the insertion part 2 enters the insertion slot, the stop block 303 is squeezed into the insertion slot along the inclined surface, further, the stop block 303 is constrained by the inner wall of the slot, the spring sheet 3 is moved into the accommodation groove 201, with further movement of the insertion part 2, the stop block 303 is moved to the recess of the insertion slot, under the elastic force of the spring sheet 3, the stop block 303 is clamped into the recess, the stop block 303 is matched with the recess, at this time, the insertion part 2 is clamped into the instrument, the handle can be manually held to drive the instrument.

[0042] After the handle is used, the boss 301 is pressed, one end of the spring sheet 3 is pressed into the accommodation groove 201, the spring sheet 3 drives the stop block 303 to be separated from the recess of the insertion slot, further, the insertion part 2 can be pulled out from the insertion slot, and the handle is removed from the instrument.

[0043] Of course, the above content is only the preferred embodiment of the present application, and cannot be considered as limiting the scope of the embodiment of the present application. The present application is not limited to the above examples, and the equivalent changes and improvements made by the ordinary skilled in the art within the essential scope of the present application should be attributed to the patent coverage range of the present application.
