Referring to fig. 4, the spring 3345 has an upper top portion 33451 and a lower top portion 33452 that are respectively disposed on the saw slot 3312, and the engaging seat 3344 has an upper protrusion 33441 that can press the upper top portion 33451 and a lower protrusion 33442 that can press the lower top portion 33452, meanwhile, in the embodiment, a groove 33440 is formed on the engaging seat 3344 opposite to the sliding block 3342, and a sliding protrusion 33420 is protruded on the sliding block 3342 opposite to the groove 33440, so that the sliding block 3342 can be inserted into the groove 33440 through the sliding protrusion 33420 to fix the engaging seat 3344.

Referring to fig. 5, when the retaining ring 3332 is released, the retractable length of the upper and lower frames 41, 42 of the frame can be quickly adjusted, and the pushing member 3346 pushes the sliding block 3342 to move up and down the engaging seat 3344 until the sliding protrusion 33420 extends into the recess 33440, so that the engaging seat 3344 is fixed down, so that when the upper frame 41 and the lower frame 42 are adjusted in a retractable manner, the upper rod 331 and the lower rod 332 synchronously adjust in a retractable manner, and when the upper rod 331 moves in an upward direction, the spring 3345, the spring seat 3343 and the lower rod 332 synchronously move up, and at this time, because the engaging seat 3344 is fixed down by the sliding block 3342, the spring seat 3343 moves up, the upper cam 3341 pushes the upper top portion 33451 of the spring 3345, so that the upper top portion is separated from the serrated groove 3312, and the spring 3345 only has the serrated portion 33452 on the upper portion 3312, the fixing force of the spring 3345 on the upper rod 331 is reduced, so that when the upper rod 331 is continuously pulled again, the spring 3345 will make the lower top detent portion 33452 disengage and engage with the serrated groove 3312 in a reciprocating manner as the upper rod 331 is pulled downward, and the upper rod can be stretched on the lower rod 332 to be adjusted to a desired length.

Conversely, when the upper and

lower frames

41, 42 are to be shortened in length, referring to fig. 7, that is, when the upper rod 331 retracts toward the lower rod 332, the upper rod 331 will link the lower rod 332, the spring seat 3343, and the spring 3345 to move toward the lower rod, at this time, when the engaging seat 3344 is fixed by the sliding block 3342, and when the spring seat 3343 moves downward, the lower engaging portion 33452 of the spring 3345 is pressed by the lower cam 33442, so that the spring 3345 only remains the upper engaging portion 33451 to be engaged with the serrated groove 2, and the engaging force of the spring 3345 to the upper rod 331 will be reduced, so that the upper rod 331 can retract toward the lower rod 332 to adjust the retraction to the required length, thereby quickly completing the length adjustment of the frame 4 and the connector 33, and effectively increasing the convenience of use.

Referring to fig. 8, after the fastening set 333 is fastened, the fastening set 333 pushes the sliding block 3342 to separate the sliding block 3342 from the engaging seat 3344 to separate the sliding protrusion 33420 from the recess 33440, so that the engaging seat 3344 is not fixed by the sliding block 3342, and the spring 3345 on the spring seat 3343 can tightly clamp the upper rod 331 to form a fixed state between the upper rod 331 and the lower rod 332, so that when the brake handle 31 acts on the upper rod 331 during braking, the upper rod 331 can be used to link the lower rod 332, and the spring seat 3343, the spring 3345 and the engaging seat 3344 can also move synchronously to link the lower rod 332 to actuate the brake 32.

Referring to fig. 9, the second preferred embodiment of the present invention, the components mentioned in this embodiment and the first embodiment and the intended purpose and effect are the same as those of the first embodiment, and it is needless to describe, particularly, in this embodiment, an actuating groove 311 is formed on the braking handle 31, a braking fixer 34 is disposed between the upper rod 331 and the braking handle 31, the braking fixer 34 has a housing 341 fixed on the upper frame 41, a shaft 342 fixed on the housing 341 and passing through the actuating groove 311, a hook member 343 disposed on the housing 341, a connecting wire 344 connected with the upper rod 331 and passing through the rear end of the braking handle 31 and fixed on the housing 341, and the hook member 343 has a concave braking groove 3431 for supporting the front end of the braking handle 31, and a fixing groove 3432 disposed above the braking groove 3431, and in this embodiment, the brake handle 31 is provided with a guide wheel 345, so that the connecting wire 344 is fixedly arranged on the housing 341 after passing through the guide wheel 345, thereby preventing the connecting wire and the brake handle 31 from reducing abrasion in the actuating process; furthermore, in the present embodiment, the brake fixer 34 further includes an upper rod seat 346 disposed on the upper rod 331 and between the upper rod seat 346 and the connecting line 344, and a resilient member 347 disposed between the upper rod seat 346 and the housing 341, the resilient member 347 presses the upper rod seat 346, so that the connecting line 344 can be kept in a tightened state at any time, and the brake handle 31 is more smoothly braked, and the embodiment is exemplified by the guide wheel 345, the upper rod seat 346, and the resilient member 347.

Referring to fig. 10, in a braking operation, when the braking handle 31 is held, the front end of the braking handle 31 is pushed by the braking groove 3431 when the braking handle 31 moves upward, and when the braking handle 31 moves upward, the guide wheel 345 is driven to move upward, and the connecting wire 344 and the upper rod seat 346 are pulled, so that the upper rod 331 is synchronously linked to achieve a braking effect, and when the hand is released, the resilient member 347 pulls the upper rod seat 346 to move, and meanwhile, in the moving process of the upper rod seat 346, the connecting wire 344 and the guide wheel 345 are linked to move downward, so that the braking handle 31 returns to an undrawn state.

Referring to fig. 11, when braking is to be performed, the braking handle 31 is pressed downward, so that the front end of the braking handle 31 is clamped on the fixing groove 3432, and in the clamping process, the braking handle 31 also drives the guide wheel 345 to move upward, so as to pull the connecting wire 344 to achieve the effect of fixing braking, and when the hand is released, because the front end of the braking handle 31 is clamped on the fixing groove 3432, the braking handle 31 can be fixed without returning to the non-braking state, so as to achieve the effect of fixing braking, and after the end of the braking handle 31 is moved out of the fixing groove 3432, the braking handle 31 returns to the non-braking state after releasing the hand; therefore, with the design of the brake handle 31, the fixing groove 3432 and the brake groove 3431, it is only necessary to use the brake handle 31 to control the brake 32 to perform the braking during the ordinary driving, or to control the brake 32 to be locked and fixed.

To sum up the above, the concealed brake device of the present invention, through the design of the adjustment set and the buckle set of the brake device, can quickly adjust the telescopic length of the upper frame and the lower frame of the frame by loosening the buckle set, and at the same time, the lower rod of the adjustment set is fixed, so that the upper rod and the lower rod form a non-linkage state, so that when the upper frame and the lower frame are pulled apart, the upper rod can synchronously adjust the telescopic adjustment, and after the adjustment is completed, the upper frame and the lower frame are fixed by the buckle set as long as the buckle set is fixed, and the lower rod is not fixed by the adjustment set, so that the upper rod and the lower rod form a linkage state, thereby quickly completing the length adjustment of the frame and the connector, and effectively increasing the convenience of use; in addition, the structure of the brake fixer can be arranged at proper time, so that multiple modes such as controlling the brake to brake a common running room or controlling the brake to be locked and fixed can be achieved through the brake handle.

The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes will occur to those skilled in the art.
