[0033] In this embodiment, the number of the first rod body 250, the second rod body 251, the third rod body 252, the pin shaft 253 and the clamping jaw 260 is two groups, and the head body 270 is clamped between the two groups of clamping jaws 260, and the shape of the head body 270 is rectangular, which is convenient for clamping and fixing.

[0034] Specifically, hold the grip holder 210 and the grip handle 220, drive the grip handle 220 to rotate, drive the connecting rod 230 to move through the grip handle 220, drive the rotating joint 240 to move through the connecting rod 230, drive the two groups of first rod bodies 250 to rotate through the rotating joint 240, drive the two groups of second rod bodies 251 and third rod bodies 252 to rotate as a whole under the action of the fulcrum of the pin shaft 253 through the two groups of first rod bodies 250, and then drive the two clamping jaws 260 to open outward, and the two sides of the scanning head body 270 are released.

[0035] As shown, Figure 2 Further, the connecting rod 230 is fixedly connected with an L-shaped rod 300, one end of the L-shaped rod 300 is fixedly connected with a supporting plate 310, the supporting plate 310 abuts against the bottom of the head body 270; the top end of the L-shaped rod 300 is slidably connected with the inner top of the shell 100, the movement of the connecting rod 230 will synchronously drive the L-shaped rod 300 to move, the L-shaped rod 300 in turn drives the supporting plate 310 to move, at this time, the bottom of the scanning head body 270 is released, the scanning head body 270 is disassembled through cooperation with the two clamping jaws 260, and vice versa, and in this process, only the grip holder 210 and the grip handle 220 need to be held.

[0036] Embodiment two

[0037] Based on Embodiment 1, a spring 430 is provided to ensure that the connecting rod 230 returns to its original position in a timely manner.

[0038] like Figure 2 As shown, in this embodiment, a fixed sleeve 400 is fixedly connected to the outside of the connecting rod 230, and a movable sleeve 410 is slidably fitted onto the outside of the connecting rod 230. Support rods 420 are fixedly connected to both ends of the movable sleeve 410. The outer ends of the two support rods 420 are fixedly connected inside the outer shell 100. A spring 430 is fitted onto the outer shell of the connecting rod 230. One end of the spring 430 is fixedly connected to the fixed sleeve 400, and the other end of the spring 430 is fixedly connected to the movable sleeve 410. It should be noted that both sides of the support plate 310 are slidably connected to the inner side of the outer shell 100, which can provide a damping effect and prevent the spring 430 from rebounding.

[0039] Specifically, during the movement of the linkage 230, the spring 430 will extend and retract, and the spring 430 will provide elastic force so that the handle 220 can return to its original position in time.

[0040] Working principle: First, grasp the grip 210 and handle 220, causing the handle 220 to rotate. The handle 220 drives the connecting rod 230 to move, which in turn drives the rotating joint 240 to move. The rotating joint 240 drives the two sets of first rods 250 to rotate, which in turn drives the two sets of second rods 251 and third rods 252 to rotate as a whole under the fulcrum of the pin 253. This causes the two grippers 260 to open outward, releasing the two sides of the scanning head body 270. At the same time, the movement of the connecting rod 230 will synchronously drive the L-shaped rod 300 to move, which in turn drives the support plate 310 to move. At this time, the bottom of the scanning head body 270 is released. Through the cooperation of the two grippers 260, the scanning head body 270 can be disassembled, and vice versa. During this process, you only need to grasp the grip 210 and handle 220.

[0041] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0042] Furthermore, it should be understood that although the specification is described in terms of embodiments, not every embodiment includes every feature described. The specification can include implicit combinations of explicitly mentioned features and / or explicit combinations of implicitely mentioned features.
