The elastic member 45 is a compression spring, one end of which is sleeved in the receiving hole 415 of the operating member 41, and the other end bounces against the bottom surface of the extension member 20. The elastic force of the elastic member 45 keeps the extension member 20 relative to the main body. 10 Generate positioning.

As shown in FIG. 3 , it is shown that the extended workbench is in the minimum use length state. At this time, the extension member 20 approaches the side end surface 14 of the main body 10, and as shown in FIGS. 6 and 7 , the operating member 41 The pulling part 412 is subjected to the elastic force of the elastic part 45, so that the movable end 414 has a distance from the bottom surface of the extension part 20, and the catch part 42 is driven by the swivel part 411, making the arc The part 421 abuts against the first latched surface 334 of the first partition 331, and the latching part 422 pushes the third latched surface 431 of the connector 43 to displace the connector 43 to the left side of FIG. 7 , Utilize the function of the connecting piece 43 to move the connecting rod 441 to the left side of FIG. surface 344, at this time, the fixing member 44 exerts its clamping function so that the first sliding bar 33 and the second sliding bar 34 of the guiding unit 30 are positioned relative to the main body 10, and the extension member 20 is also relatively The main body 10 is kept in position.

When wanting to adjust the use length of the extension workbench, as shown in Figure 9 and Figure 10, the operator presses the movable end 414 of the operating part 41 toward the extension part 20 (the elastic part 45 is compressed), the The detent 42 is driven by the swivel part 411, so that the release part 423 will rotate and correspond to the third detent surface 431, and the maximum distance d1 between the detent part 422 and the axis L is greater than the The function of the minimum distance d2 between the release part 423 and the axis L will make the arc part 421 not abut against the first constrained surface 334 of the first partition 331, and the detent part 422 will not push the The third clamped surface 431 of the connecting piece 43, so that the connecting piece 43 and the connecting rod 441 linked with the connecting piece 43 are released, and the clamping plate 442 is not clamped by the connecting rod 441. Made on the second clamped surface 344 of the second partition 341, at this time, the clamping function of the fixing member 44 has been released, so that the extension member 20 is transformed into an unpositioned state relative to the main body 10, and the guide The first slide bar 33 and the second slide bar 34 of the lead unit 30 can be displaced relative to the main body 10, and the operator can pull the extension piece 20 to move outward relative to the main body 10, so as to adjust the use of the extension workbench. length purpose.

After the adjustment, the operator releases the pressing effect on the operating member 41, and the elastic force of the elastic member 45 can be used to make the operating member 41 link with the locking member 42 to rotate around the axis L as the rotation center, and make the operating member 41 The arc portion 421 abuts against the first clamped surface 334 of the first partition 331 , the detent portion 422 pushes the third clamped surface 431 of the connecting piece 43 , and makes the connecting piece 43 drive the connecting rod 441 , the connecting rod 411 drives the clamping plate 442 perpendicular to the axis L to clamp the second slide bar 34 of the guide unit 30 , so that the extension member 20 can return to the positioned state relative to the main body 10 , As shown in Figure 6 and Figure 7.

Therefore, under normal conditions, the present invention utilizes the elastic action of the elastic member 45 to enable the catch portion 422 of the catch member 42 to catch the connecting member 43, and the connecting member 43 indirectly drives the splint 442 to clamp On the second latched surface 344 of the second slide bar 34 , the extension member 20 is urged to maintain a position relative to the main body 10 . When pressing the movable end 414 of the operating part 41, the locking of the connecting part 43 by the locking part 42 can be released, the connecting part 43 links the connecting rod 441, and the splint 442 is separated from the second connecting part. The second clamping surface 344 of the two partitions 341 is clamped, and the extension piece 20 can be operated simultaneously to drive the first slide bar 33 and the second slide bar 34 relative to the first guide rail 31 and the second guide rail 32 Sliding is generated, and the extension member 20 is adjusted to be displaced relative to the main body 10, so only one hand is required for operation, and the overall structure is simple and the operation is quite convenient.

It is worth mentioning that the present invention utilizes the guide unit 30 to connect the extension piece 20 and the main body 10 so that the extension piece 20 can slide relative to the main body 10, and the detent unit 40 can be used relative to the main body 10. The operation part 41 rotated by the extension part 20 and the detent part 42 driven by the operation part 41 cooperate with the connecting part 43 and the fixing part 44 to make the extension part 20 relative to the main body 10 produce positioning and non-positioning Transition between two states. Therefore, the functions of the guide unit 30 and the detent unit 40 of the present invention are different from the first guide rod and the detent unit of Taiwan Publication No. 201143998.
