[0027] Please see Figure 1-4This utility model provides a mouse quick grasping and fixing device, including an operation plate 1, four limiting blocks 2 are installed on the upper end of the operation plate 1, and a grasping and fixing structure is embedded between the four limiting blocks 2. The grasping and fixing structure includes a handle 3, a mounting rod 4, a fixing plate 5, four hinges 6 and two grasping and fixing covers 7.

[0028] The bottom end of the handle 3 is movably embedded between four limiting blocks 2. The bottom end of the mounting rod 4 is fixedly installed at the center of the upper end of the handle 3. The fixing plate 5 is fixedly installed at the upper end of the mounting rod 4. One end of each of the four hinges 6 is connected to the four corners of the fixing plate 5. One end of each of the two gripping fixing covers 7 is connected to the other end of each of the four hinges 6.

[0029] It should be noted that when grasping and fixing the mouse, the operator first removes the handle 3 from the four limiting blocks 2 at the top of the operating plate 1, then holds the handle 3 and hooks the opening and closing drive structure with their fingers. Under the action of the four hinges 6, the two grasping and fixing covers 7 unfold outward at the bottom of the fixing plate 5. The operator then moves the two grasping and fixing covers 7 above the mouse using the handle 3, and then releases the opening and closing drive structure with their fingers, causing the two grasping and fixing covers 7 to reset and close, thus grasping the mouse. The handle 3 is then inserted back into the four limiting blocks 2, and the grasping and fixing structure is supported by the operating plate 1. The operator then fixes the two ends of the strap to the top of the fixing rod 16 in the operating groove 14 to fix the mouse, and then the operation such as drug injection can be performed.

[0030] refer to Figure 1 In this embodiment, the connection between the two gripping fixing covers 7 and the mounting rod 4 is provided with an opening and closing drive structure. The opening and closing drive structure includes two first hinge seats 8, a movable sleeve 9, two second hinge seats 10, two drive rods 11, two connecting rods 12 and two springs 13.

[0031] Two first hinge seats 8 are respectively installed at the center of the outer wall of the two gripping and fixing covers 7. The movable sleeve 9 is movably fitted onto the upper end of the mounting rod 4. Two second hinge seats 10 are respectively installed on the outer walls of both sides of the movable sleeve 9. The two ends of the two drive rods 11 are respectively connected to the two first hinge seats 8 and the two second hinge seats 10. Two connecting rods 12 are respectively installed on the outer walls of both sides of the movable sleeve 9. One end of the two springs 13 is respectively connected to the two connecting rods 12, and the other end is respectively connected to both sides of the handle 3.

[0032] It should be understood that when grasping the mouse, the operator hooks the two connecting rods 12 with their fingers, causing the two connecting rods 12 and the movable sleeve 9 to move upward at the upper end of the mounting rod 4, changing the distance between the movable sleeve 9 and the fixed plate 5. At the same time, under the connection of the second hinge seats 10 on both sides of the movable sleeve 9, the two drive rods 11 drive the two first hinge seats 8 to move, thus achieving the purpose of unfolding the two grasping and fixing covers 7. When the two grasping and fixing covers 7 are above the mouse, the fingers release the two connecting rods 12. Under the rebound action of the spring 13 between the connecting rods 12 and the handle 3, the movable sleeve 9 quickly returns to its original position. Under the transmission action of the first hinge seats 8, the second hinge seats 10, and the drive rods 11, the two grasping and fixing covers 7 quickly close.

[0033] In some embodiments, reference Figure 1 The upper end of the gripping and fixing cover 7 is provided with several operating slots 14. Both sides of the gripping and fixing cover 7 are provided with side plates 15. Fixing rods 16 are installed in the several operating slots 14. A connecting reinforcing rib 17 is provided at the connection between the fixing plate 5 and the mounting rod 4. A connecting sleeve 18 is provided at the connection between the drive rod 11 and the first hinge seat 8 and the second hinge seat 10.

[0034] Meanwhile, the side plate 15 can block and close the two sides of the gripping and fixing cover 7, and the several operating slots 14 and several fixing rods 16 can connect and fix the straps to ensure the overall fixation effect of the mouse. The connecting sleeve 18 can ensure the connection stability between the drive rod 11 and the first hinge seat 8 and the second hinge seat 10.

[0035] In summary, when grasping and fixing the mouse, the operator first removes the handle 3 from the four limiting blocks 2 at the top of the operating plate 1. Then, holding the handle 3, the operator hooks the two connecting rods 12 with their fingers, causing the two connecting rods 12 and the movable sleeve 9 to move upward at the top of the mounting rod 4, changing the distance between the movable sleeve 9 and the fixing plate 5. At the same time, under the connection of the first hinge seats 8 on both sides of the movable sleeve 9, the two drive rods 11 drive the two second hinge seats 10 to move.

[0036] Under the action of the four hinges 6, the two gripping and fixing covers 7 are opened outward at the lower end of the fixing plate 5. Then, the staff moves the two gripping and fixing covers 7 above the mouse through the handle 3. The fingers release the two connecting rods 12. Under the rebound action of the spring 13 between the connecting rod 12 and the handle 3, the movable sleeve 9 is quickly reset. Under the transmission action of the first hinge seat 8, the second hinge seat 10 and the drive rod 11, the two gripping and fixing covers 7 are quickly closed to grasp the mouse. Then, the handle 3 is embedded into the four limiting blocks 2 again. The gripping and fixing structure is supported by the operating plate 1. Then, the staff fixes the two ends of the strap to the upper end of the fixing rod 16 in the operating groove 14 to fix the mouse. Then, drug injection and other operations can be performed.

[0037] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
