Referring to fig. 1 and 3, the telescoping mechanism 20 includes a driving member 21, a transmission assembly 22, a reset member 23 and a locking assembly 24. The driving part 21 is connected with the input end of the transmission assembly 22, each electric pulse comb tooth 41 is installed at the output end of the transmission assembly through the comb plate 42, the reset part 23 and the locking assembly 24 are both connected on the transmission assembly 22, the output end of the transmission assembly 22 can output reciprocating linear motion, namely, after each electric pulse comb tooth 41 is installed at the output end of the transmission assembly 22, the telescopic motion of the electric pulse comb tooth 41 can be realized.

The driving member 21 may be driven manually or electrically. The drive element 21 can output linear movements as well as rotational movements.

The transmission assembly 22 includes a plurality of transmission members connected in series. Wherein, the quantity of driving medium is injectd according to actual demand, can be fixed connection between each driving medium, also can be transmission connection. The transmission assembly 22 composed of the transmission members can output linear motion under the driving of the driving member 21.

The locking assembly 24 can lock the movement of each transmission member after the driving member 21 drives each transmission member once to move for a preset stroke, that is, when the driving member 21 drives each transmission member for the first time, and after each transmission member moves for a preset stroke, the locking assembly 24 locks the movement of each transmission member, so that the position of the output end of the transmission assembly 22 is kept unchanged, and further the position of each electric pulse comb 41 is kept unchanged, and the working stability is good. And the locking assembly 24 can unlock the movement of each transmission member after the driving member 21 is driven for the second time, that is, after the driving member 21 is started for the second time, the locking assembly 24 will unlock the movement of each transmission member.

Here, the preset stroke is a stroke that is preset to be extended corresponding to the electric pulse comb 41, that is, a stroke that is preset to be extended in the telescopic mechanism 20 and is converted into a stroke that is required to move each transmission element. This predetermine stroke and correspond different types of driving medium and can establish to straight line stroke and rotation stroke, for example when the driving medium is the gear, should predetermine the stroke and be the rotation stroke, when the driving medium is the rack, should predetermine the stroke and be straight line stroke.

The reset piece 23 is installed on a transmission piece and used for driving each transmission piece to reset after the transmission pieces are unlocked. It should be noted that the reset member 23 and the locking assembly 24 may be mounted on the same transmission member or on different transmission members, but preferably are mounted on different transmission members. In fact, the reset member 23 and the locking assembly 24 are mounted on different transmission members. Reset 23 and be energy storage spare, it can store the kinetic energy before the driving medium locking, then when the driving medium unblock back, reset 23 and can release energy to drive each driving medium and driving piece 21 and reset.

The fixing member 241 is fixedly disposed, and specifically, the fixing member 241 is mounted on an inner bracket of the housing 10, so that the fixing member 241 is kept fixed during the movement of each transmission member. The movable structure is connected to a transmission member, and the movable structure will move along with the movement of the transmission member, and the movable structure can be locked on the fixing member 241 or released from the fixing member 241 under the driving of the transmission member. When the driving member 21 is started for the first time, the driving member 21 drives each transmission member to move, and then the movable structure can move relative to the fixing member 241 and lock on the fixing member 241 after each transmission member moves for a preset stroke, so that the movement of each transmission member is locked and cannot retreat; when the driving member 21 is started for the second time, the driving member 21 drives each transmission member to move, so as to drive the movable structure to be disengaged from the fixing member 241, and each transmission member is reversely reset under the driving of the reset member 23.

In an embodiment, referring to fig. 7 to 9, a bent guide path 50 is formed on the fixed member 241, and a first sliding portion 2441 is disposed on the movable structure. The first sliding portion 2441 can slide along the guide path 50 under the driving of the driving member, and changes the sliding direction or forms a one-way lock at the inflection point of the guide path 50. Specifically, when the driving member 21 is positively started for the first time, the driving member drives the movable structure to move, so that the first sliding portion 2441 slides for a distance along the guide path 50 and changes the sliding direction after sliding for a distance, and a one-way lock is formed; specifically, the first sliding part 2441 changes direction after sliding forward for a certain distance and is locked in one direction, that is, the first sliding part 2441 is locked after moving in the reverse direction; after the driving member 21 is started forward for the second time, the driving member 21 drives each transmission member to move, so as to drive the first sliding portion 2441 to slide forward along the guiding path 50, thereby unlocking the movable structure on the fixing member 241, and then each transmission member is driven by the reset member 23 to reset reversely. In this embodiment, the guide path 50 and the first sliding portion 2441 are cooperatively disposed, so that the locking and unlocking structure of the movable structure and the fixed member 241 is simple, the processing and manufacturing are simple, and the cost is low. In addition, through the bent arrangement of the guide path 50, the first sliding portion 2441 changes the sliding direction or forms a one-way locking at the inflection point of the guide path 50, so that the driving element 21 is started in the forward direction at one time to lock the reverse movement of the movable structure, and the driving element 21 is started in the forward direction at the second time to unlock the movable structure from the fixing element 241, which is simple in operation.

It should be noted that the forward movement of the driving element 21, the forward movement of the transmission element, and the forward movement of the first sliding portion 2441 all refer to the movement made by the driving element 21, the transmission element, and the first sliding portion 2441 when the telescopic mechanism 20 makes the extending movement; conversely, the reverse movement of the driving member 21, the reverse movement of the transmission member, and the reverse movement of the first sliding portion 2441 all refer to the movement of the driving member 21, the transmission member, and the first sliding portion 2441 when the telescopic mechanism 20 performs the retracting movement.

In a specific embodiment, referring to fig. 7, the guiding path 50 includes a leading-in section 51, a locking section 52 and a leading-out section 53, and the leading-in section 51, the locking section 52 and the leading-out section 53 are connected in sequence. The locking section 52 is located in the middle, the leading-in section 51 is used for guiding the first sliding portion 2441 to slide into the locking section 52, and the leading-out section 53 is used for guiding the first sliding portion 2441 to be reset after being unlocked from the locking section 52. The locking section 52 is formed with a first inflection point 54, a second inflection point 55 is formed at the junction of the introduction section 51 and the locking section 52, a third inflection point 56 is formed at the junction of the locking section 52 and the derivation section 53, the first inflection point 54 is located at the trough, and the second inflection point 55 and the third inflection point 56 are located at the peak. Specifically, the locking section 52 is V-shaped and forms a first inflection point 54 at the inflection point. It is understood that in other embodiments of the present application, the locking segment 52 may also be U-shaped or other bent shape with a first inflection point, and is not limited herein.

In operation, the first sliding portion 2441 slides along the lead-in section 51 when the driver 21 is driven in the forward direction and slides into the locking section 52 at the second inflection point 55 to form a one-way lock. Specifically, since the moving direction of the first sliding portion 2441 is changed from the forward direction to the reverse direction by the second inflection point 55, the driving of the driving member 21 is stopped, and the first sliding portion 2441 can move reversely only along the locking section 52. The locking section 52 has a first inflection point 54, and the first inflection point 54 is located at the position of the trough, so that the first sliding portion 2441 cannot continue to move reversely at the first inflection point 54, that is, the first sliding portion 2441 forms a reverse lock at the first inflection point 54, and the entire telescopic mechanism 20 forms a reverse lock.

The first sliding portion 2441 slides from the locking section 52 into the lead-out section 53 via the third inflection point 56 during the second forward driving of the driver 21. Specifically, when the driving member 21 is driven forward for the second time, the first sliding portion 2441 slides forward at the first inflection point 54 and reaches the third inflection point 56, the sliding direction of the first sliding portion 2441 changes from the forward direction to the reverse direction, and when the driving member 21 stops driving when the third inflection point 56 is reached, the first sliding portion 2441 slides in the reverse direction along the guiding section 53 under the driving of the resetting member 23, and each transmission member moves in the reverse direction under the driving of the resetting member 23, so as to drive the massage member to contract.

Note that the driving of the driver 21 is stopped at the second inflection point 55 or the third inflection point 56; since the direction is reversed when the first sliding portion 2441 meets the inflection point, the driving member 21 receives resistance, thereby stopping the driving. Specifically, if the driving member 21 is manually driven, the driving may be stopped according to the hand feeling, and if it is electrically driven, the driving may be stopped according to the sensor.

Specifically, the first sliding portion 2441 can stop at the first inflection point 54 of the locking segment 52 and can move only away from the first inflection point 54, i.e., can move only in one direction. In actual operation, the movable structure moves linearly under the driving of the transmission member, the first sliding portion 2441 slides along the guiding section 51, and when the movable structure slides to the locking section 52, the first sliding portion 2441 slides downwards to the tip end of the locking section 52 under the guiding of the locking section 52; with the drive of the transmission element, the first sliding portion 2441 slides out of the locking section 52 and enters the lead-out section 53, guided by the locking section 52.
