As shown in fig. 2 and 3, the second guide plate 12 also has guide holes 121, 122 having a rectangular shape. The guide holes 121 and 122 are disposed opposite to the guide holes 111 and 112 of the first guide plate 11, respectively. The driving part 15 is an integrally formed U-shaped plate including a fixing plate 153 connected to the contact pressure springs 171, 172, 173, and a first driving plate 151 and a second driving plate 152 at opposite ends of the fixing plate 153, wherein the first driving plate 151, the second driving plate 152 and the second guide plate 12 are parallel to each other.
Fig. 4 is a further exploded view of the drive arrangement shown in fig. 3. As shown in fig. 4, the first drive plate 151 has substantially rectangular drive holes 1511, 1512 and guide pin holes 1513. The arrangement direction of the drive holes 1511, 1512 is parallel to the line L1. The first drive plate 151 and the second drive plate 152 are identical, and the second drive plate 152 has drive holes 1521, 1522 and guide pin holes (not shown in fig. 4) disposed opposite the drive holes 1511, 1512 and the guide pin holes 1513.
The driving device 1 further includes a guide pin 18, the guide pin 18 passes through the guide pin hole 1513 of the first driving plate 151 and the guide pin hole of the second driving plate 152, and both ends of the guide pin 18 are fixed to the first guide plate 11 and the second guide plate 12, respectively.
The transmission member 16 includes a first pin 161 and a second pin 162, the first pin 161 and the second pin 162 are parallel to each other, and the straight line L1 is located on a plane where the first pin 161 and the second pin 162 are located. The driving device 1 further includes a roller 165 between the first and second pins 161 and 162, and first and second connecting rods 163 and 164 perpendicular to the first and second pins 161 and 162. The first connecting rod 163 is connected to one ends of the first pin 161, the roller 165, and the second pin 162, and the second connecting rod 164 is connected to the other ends of the first pin 161, the roller 165, and the second pin 162.
Referring again to fig. 3, the first pin 161 passes through the driving hole 1511 of the first driving plate 151 and the driving hole 1521 of the second driving plate 152. The second pin 162 passes through the drive hole 1512 of the first drive plate 151 and the drive hole 1522 of the second drive plate 152. The rotating main shaft 19 is provided with a cam 191, and when the rotating main shaft 19 rotates to drive the cam 191 thereon to rotate and drive the roller 165 to move along the direction of the straight line L1, the roller 165 can simultaneously drive the first pin 161, the second pin 162, the first connecting rod 163 and the second connecting rod 164 to move together, so as to push the driving component 15 to move together.
Fig. 5 is a schematic plan view of the driving part shown in fig. 4 viewed in the direction indicated by the arrow a. As shown in fig. 5, the guide pin hole 1513 is configured such that the driving member 15 moves relative to the guide pin 18 along a line L2 (dashed line shown in fig. 5), wherein the line L1 is perpendicular to the line L2. When the first pin 161 and the second pin 162 apply a force to the driving member 15, the force may cause the driving member 15 to move along the line L2.

When the first pin 161 and the second pin 162 move along the line L1 from the second pin 162 to the first pin 161, the driving force exerted by the first pin 161 and the second pin 162 on the driving member 15 will make the driving member 15 move along the line L2 from the fixed plate 153 to the supporting plate 13, and the driving member 15 will simultaneously drive the contact pressure springs 171, 172, 173 fixed on the fixed plate 153 to move. When the driving member 15 moves to the closing position, the closing holding means (not shown in fig. 7) is engaged to stop the driving member 15, and finally the driving member 1 is in the closing state shown in fig. 7. The movement process of the driving device 1 from the closing state to the opening state is opposite to the above process, and is not described again.
The driving device 1 of the present invention does not adopt a multi-link mechanism, and therefore, the number of parts is small and the cost is low.
In the driving device 1 of the present invention, the driving member 16 moving along the line L1 directly pushes the driving member 15 to move along the line L2, and the driving member 15 simultaneously drives the three contact pressure springs to move integrally, so that the driving chain is simple and the safety performance is high.
The driving member 15 of the present embodiment is an integrally formed U-shaped plate, and has a simple structure and low manufacturing and assembling costs. The driving member 15 is located in the substantially rectangular parallelepiped accommodation space 14 defined by the first guide plate 11 and the second guide plate 12, so that the driving device 1 is compact and small in size as a whole. And the two parallel first and second drive plates 151 and 152 further ensure that the drive member 15 moves along a line L2.
