Specific implementation mode
The utility model is described in detail below with reference to attached drawing and in conjunction with the embodiments.It should be noted that not rushing
In the case of prominent, the features in the embodiments and the embodiments of the present application can be combined with each other.
In the description of the present invention, it should be understood that the side of the instructions such as term " left side ", " top ", " bottom "
Position or position relationship are to be based on the orientation or positional relationship shown in the drawings, and are merely for convenience of description the utility model and simplification is retouched
It states, does not indicate or imply the indicated device or element must have a particular orientation, with specific azimuth configuration and operation,
Therefore it should not be understood as limiting the present invention.
Fig. 1 shows a kind of structural schematic diagram of adjustable support device of the utility model.One kind as shown in Figure 1 can
The support device of adjusting includes：Support pin pipe 101, positioning chamber 103, support axis pin 106, positioning wedged block 107 and spring 111, knot
It closes Fig. 2 to further illustrate, above-mentioned support pin pipe 101 is cylindrical tube with support axis pin 106, and 101 center of support pin pipe is provided with center
Hole 102 allows support axis pin 106 to be plugged in support pin pipe 101 and forms existing common telescopic rod, above-mentioned support pin pipe
101 extend the positioning chamber 103 there are one diameter slightly larger than support pin pipe 101,103 top wall surface of positioning chamber at left end face
On open there are one the fixture block mounting hole 104 of 103 top wall surface of positioning chamber is cut through, the diameter of above-mentioned fixture block mounting hole 104 selects greatly
In the centre bore 102 of support pin pipe 101, fixture block is fixed after so that support axis pin 106 is passed through centre bore 102 and fixture block mounting hole 104
There are the setting that gap surplus is convenient for positioning wedged block 107, above-mentioned positioning wedged block 107 preferably circular, positioning wedged blocks in hole 104
107 centers, which are provided with to wear, connects hole 108, and the diameter for wearing connection hole 108 is namely more than support axis pin 106 more than centre bore 102, this
Sample positioning wedged block 107 can be moved arbitrarily after being sleeved on support axis pin 106, and above-mentioned positioning chamber 103 is also seen that from Fig. 2
It is opened in bottom wall there are one the rectangle adjustment hole 105 placed vertically, adjustment hole 105 is preferably located at the center of positioning chamber 103,
Certainly also to deviate center, adjustment hole 103 is through-hole, is positioned such that 107 opposite sides of fixture block each extends over fixed block 110 and adjusts
After locking nub 109, the fixed block 110 of positioning wedged block 107 deeper can be inserted in adjustment hole 105, and due to the utility model
105 diameter of adjustment hole it is preferably bigger than fixed block 109, be positioned such that fixture block 107 can be left and right back and forth along support axis pin 106
It overturns, but such structure can not be such that support device fixes, therefore on the basis of above structure, above-mentioned spring 111 needs
It is socketed on support axis pin 106, and spring 111 is between 103 inner wall of positioning wedged block 107 and positioning chamber, it can from Fig. 1
Know, above-mentioned spring 111 is preferably fixed to the positioning wedged block 107 and positioning chamber that left side is namely fixed on 106 side of support axis pin
Between 103 inner walls.
Adjustable support device with the above structure, when support axis pin 106 penetrates branch from 101 right side of support pin pipe
After supportting in pin pipe 101, hole 108 and spring 111 are connected being worn across positioning wedged block 107, is pierced by from 101 left side of support pin pipe, by
Make positioning wedged block 107 tilt in the elastic force effect of spring 111 to be clamped with support axis pin 106, wearing on positioning wedged block 107 connects hole
108 will locking support axis pin 106, such fixed form due to wear connect hole 108 can random locking support axis pin 106
Position, makes the distance that adjustable support device can be formed that can arbitrarily change, and is adjusted to ideal convenient for user
Length, solve the fixed trouble of existing gear, while that such fixed form also can be more is secured, support device will not
Shake, while when the length of adjusting supporting device, only need to pull adjusting block 109, make to wear connect hole 108 not with support axis pin 106
Contact, support axis pin 106 can be moved arbitrarily, and such overall structure is simple, adjusts facility also more.
The above descriptions are merely preferred embodiments of the present invention, is not intended to limit the utility model, for this
