The rest of the structure is the same as that of embodiment 2.
With reference to fig. 1 to 3, in an initial state, under the action of the tensioning spring 201b, the free end of the connecting rod 201a extends out from the installation hole 101a, and pushes the deflection plate 202 to gradually get away from the installation hole 101a, and along with the distance of the deflection plate 202, the limiting spring 203a in the elastic member 203 returns to an original length, that is, pushes the sliding collar 203b to slide on the connecting rod 201a towards the installation hole 101a, so as to indirectly adjust the angle of the deflection plate 202, so that the open end of the deflection plate is inclined upwards, thereby facilitating the placement of the switching power supply K.
When the switching power supply K is placed, the bottom of the casing of the switching power supply K faces the second clamping plate 202c of the two deflection plates 202, and the switching power supply K is pressed to move towards the deflection plates 202, so that the casing of the switching power supply K gradually presses the two deflection plates 202, the two deflection plates 202 gradually move away from each other, the connecting rod 201a is pushed to move inwards the mounting hole 101a, and the tensioning spring 201b is pressed. When the switching power supply K is completely placed in the two deflection plates 202, the tension spring 201b is at the most complete compression, and the telescopic rods 201 at the two sides are at the same horizontal height, so that the clamping stability of the switching power supply K can be maintained. Further, as the connecting rod 201a retracts into the mounting hole 101a, the end of the mounting hole 101a blocks the sliding collar 203b and moves it on the connecting rod 201a toward the hinge ring 201c, and as the distance becomes shorter, the length of the position limiting spring 203a is compressed, i.e., the position limiting spring 203a exerts an elastic force on the side wall of the first clamping plate 202b in the deflecting plate 202, so that the lateral stability of the clamping is maintained.
When the switching power supply K needs to be taken out of the two groups of deflection plates 202, the switching power supply K is pulled out forcibly. Under the action of the tension spring 201b and the limit spring 203a, the device is restored to the initial state again. For the next replacement of the switching power supply K.
It should be noted that the above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting, and although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention can be modified or replaced with equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should be covered by the scope of the claims of the present invention.
