It should be noted that, when the fixing device is actually used to fix (lock) an electronic device, it can be used with the sleeve 500 shown in fig. 13. The specific use steps can be as follows: the sleeve body 500 is wrapped with the electronic device, the lead screw 511 is rotated, and the spacing distance between the first guide rail 513 and the second guide rail 515 is increased, so that the electronic device can be placed between the first guide rail 513 and the second guide rail 515. After the electronic device is placed, the lead screw 511 can be rotated to reduce the distance between the first guide rail 513 and the second guide rail 515, so that the electronic device is clamped by the first guide rail 513 and the second guide rail 515. At this time, the front latch end 5231 passes through the latch opening 5211 under the elastic force of the first spring 522 to extend out of the latch seat 521 and the latch hole 11 of the main support plate 10, and drives the two protrusions 5233 to move forward along the first notches 5212 respectively when extending out, so as to achieve locking. When the unlocking is performed, the unlocking key 5244 is pressed downwards to compress the second spring 5241, the cross rod 52422 moves downwards to drive the first connecting rod 52421 and the second connecting rod 52423 to move downwards to drive two second rotating rods 52433 to depart from the end part of the corner 52432 to move downwards, then two first rotating rods 52431 depart from the end part of the corner 52432 to move backwards, so that the protrusion 5233 is pushed two to move backwards along the first notch 5212 respectively to drive the front end 5231 of the lock tongue to penetrate through the lock tongue hole 11 and the lock tongue opening 5211 to retract into the lock tongue seat 521, and the sleeve body 500 and the electronic equipment wrapped by the sleeve body can be taken out.

The fixing device provided by the utility model adopts the adjustment of the screw rod 511, and after the distance between the first guide rail 513 and the second guide rail 515 is adjusted, the distance between the first guide rail 513 and the second guide rail 515 is not easy to change. Therefore, even if the clamped object is an electronic device with a large size and a heavy volume or the clamped object is in a bumpy environment, the clamped object can be clamped through the clamping assembly and is not easy to fall off, and the electronic device is fixed. In addition, the fixing device can extend the front end 5231 of the bolt out of the bolt seat 521 through the first spring 522 without external force to realize locking; the front end 5231 of the latch bolt can be retracted into the latch bolt seat 521 by pressing the unlocking button 5244 downward, so as to unlock the electronic device, and the electronic device cannot move laterally (i.e., cannot move in a direction perpendicular to the direction in which the front end 5231 of the latch bolt extends out of the latch bolt seat 521) in a locking manner, so that the electronic device is fixed. Moreover, by separating the first guide rail 513 from the first guide rail seat 514 and separating the second guide rail 515 from the second guide rail seat 516, when the first threaded through hole and the second threaded through hole connected to the screw 511 are worn and the distance between the first guide rail 513 and the second guide rail 515 cannot be fixed, only the first guide rail seat 514 and the second guide rail seat 516 need to be replaced, thereby saving the cost.

Optionally, as shown in fig. 7 and 9, a cylindrical recess 5213 is further provided at the top of the latch base 521. The cylindrical recess 5213 is used to receive the end of the second spring 5241, preventing the second spring 5241 from moving.

Alternatively, as shown in fig. 10, the first guide rail 513 is provided with a first groove 5131, and the second guide rail 515 is provided with a second groove 5151. One side of the first groove 5131 close to the main bearing plate 10 is an arc surface, and one side far away from the main bearing plate 10 is a plane. One side of the second groove 5151 close to the main bearing plate 10 is an arc surface, and one side far away from the main bearing plate 10 is a plane. The first guide 513 and the second guide 515 are arranged in a mirror image, forming a receiving space for receiving the clamped article.

For many tablet computers, the front surface (the surface on which the display screen is disposed) is larger than the back surface, and the side surface (the transition surface from the front surface to the back surface) is an arc surface. Therefore, the first guide rail 513 and the second guide rail 515 are provided with cambered surfaces matched with the side surfaces of the tablet computer, so that when the tablet computer is clamped, if the front surface of the tablet computer faces the main bearing plate 10, the tablet computer cannot be placed in the main bearing plate, and the problem that the display screen is abraded due to the fact that the front surface of the tablet computer faces downwards can be effectively prevented.

Optionally, referring again to fig. 1 and 2, the fixing device further includes: two tightening mechanisms disposed on both sides of the screw 511, each of the tightening mechanisms includes: a third spring 5171, a guide rod 5172, a first guide rod seat 5173, and a second guide rod seat 5174, wherein the first guide rod seat 5173 includes a second through hole, and the second guide rod seat 5174 includes a third through hole.

The first guide holder 5173 is connected to the first guide 513, and the second guide holder 5174 is connected to the second guide 515. One end of the guide rod 5172 passes through the second through hole, and the other end passes through the third through hole. Both ends of the third spring 5171 are respectively connected to the first guide rod holder 5173 and the second guide rod holder 5174. When the third spring 5171 contracts, the first guide rod holder 5173 and the second guide rod holder 5174 are drawn together along the axial direction of the guide rod 5172, and then the first guide rail 513 and the second guide rail 515 are drawn together along the axial direction of the guide rod 5172.

With the above arrangement, the first guide rod holder 5173 and the second guide rod holder 5174 pass through the guide rod 5172 and can slide on the guide rod 5172. When an article such as an electronic device needs to be clamped, the first guide rod seat 5173 and the second guide rod seat 5174 can be moved away from each other along the axial direction of the guide rod 5172, so as to increase the distance between the first guide rod seat 5173 and the second guide rod 5172, and further increase the distance between the first guide rail 513 and the second guide rail 515, so that the electronic device can be placed between the first guide rail 513 and the second guide rail 515. After the electronic device is placed, the third spring 5171 automatically contracts to enable the first guide rod seat 5173 and the second guide rod seat 5174 to approach along the axis direction of the guide rod 5172, and then the first guide rail 513 and the second guide rail 515 to approach along the axis direction of the guide rod 5172, so that the distance between the first guide rail 513 and the second guide rail 515 is reduced, and the electronic device is clamped by the first guide rail 513 and the second guide rail 515. Thus, the tightening mechanism can be provided to assist in clamping.

Optionally, the fixing device further comprises: two elastic members 525. One end of each elastic member 525 is connected to the guide rod 5172 of one of the tightening mechanisms adjacent to the elastic member 525, and the other end is connected to the lower guard 30.

When the electronic device wrapped with the cover body 500 is placed in the fixing device and the cover body is locked in the fixing device, the lower end of the cover body 500 is in contact with the lower baffle 30, and the elastic member 525 can be in a stretching state. When the cover 500 and the electronic device wrapped by the cover are required to be taken out, the front end 5231 of the latch leaves the lock hole 11 and retracts into the latch seat 521, and the cover 500 and the electronic device wrapped by the cover move upwards under the action of the elastic force of the elastic element 525 to partially pop out of the fixing device, so that a user can take out articles conveniently.
