Abstract
The utility model discloses a bench drill driven by a spring, aiming at providing a bench drill driven by a spring which can drive a drill to rotate without power source in case of power failure or powerless condition. The bench drill comprises a combined spring driver combined by a plurality of sets of spring units, and a drill arranged on a terminal output shaft of the spring; wherein, the combined spring driver consists of a plurality of sets of spring units; one end of a poking sleeve is provided with a poking shaft which is adapted to the shaft sleeve of a first set of spring unit, while the other end is provided with the terminal output shaft; the terminal output shaft is fixedly connected with the spring in the last set of spring unit and the fixes the drill. The rotation of the poking shaft enables the spring of each unit accumulate elasticity; when the springs release energy, the terminal output shaft of the spring is driven to rotate, thus having the beneficial effects of convenient use and energy saving.
Description
Technical field
The utility model relates to the bench drill that a kind of clockwork spring drives.
Background technology
With the motor is the bench drill of drive power source, must have a constant power supply supply could ensure its normal operation.At some in particular cases: for example outage or power free ground convenience can not guarantee its normal use.In addition, the costliness of manufacturing cost and use cost also is the deficiencies in the prior art part.
The utility model content
The purpose of this utility model is to provide a kind of bench drill that relies on clockwork spring to drive, and does not need power supply can drive the drill bit rotation, in order to cutting off the power supply or not having under the electric situation and use.
For this reason, the utility model has adopted following technical scheme: the bench drill that clockwork spring of the present utility model drives comprises the combined type clockwork spring driver that many group clockwork springs unit is formed, the drill bit of installing on the clockwork spring terminal output shaft; Described combined type clockwork spring driver is made of many groups clockwork spring unit; Every group of clockwork spring unit constitutes by clockwork spring shell, the clockwork spring, the winder that are arranged in the described clockwork spring shell, and the outer end of described clockwork spring is connected mutually with the clockwork spring shell, and the inner end and the winder of clockwork spring are connected; The sidewall of described clockwork spring shell is provided with axle sleeve; Described winder and clockwork spring shell side wall matched in clearance; Offer axis hole on an end face of winder, the winder other end extends in the axle sleeve in this clockwork spring unit; Winder one end that offers axis hole extends in the axle sleeve in the adjacent clockwork spring of the corresponding with it side unit, and its outer peripheral face is connected with this axle sleeve by ratchet mechanism, and its axis hole is connected by the winder of ratchet mechanism with this clockwork spring unit; Ratchet mechanism in the described axle sleeve is opposite with ratchet mechanism clutch direction in the axis hole, and the described clockwork spring whole units of organizing place in the dial sleeve more, and the clockwork spring shell outer peripheral face in every group of clockwork spring unit is connected with described dial sleeve inner peripheral surface by ratchet mechanism respectively; One end of dial sleeve is provided with that the axle sleeve of dial axis and first group of clockwork spring unit is suitable, and the other end is provided with the terminal output shaft, and this terminal output shaft is connected mutually with clockwork spring in last group clockwork spring unit, and fixed drill bit.
After adopting such structure, make the clockwork spring poultry of every unit amass elastic force by the turn dial axis, when clockwork spring released energy, the terminal output shaft that drives clockwork spring rotated; Therefore has beneficial effect easy to use, energy savings.
Description of drawings
Shown in Figure 1 is the schematic diagram of the utility model concrete structure.
The specific embodiment
As shown in Figure 1, the bench drill that a kind of clockwork spring described in the utility model drives comprises the combined type clockwork spring driver that many group clockwork springs unit is formed, the drill bit of installing on the clockwork spring terminal output shaft 34 56; Described combined type clockwork spring driver is made of many groups clockwork spring unit; Every group of clockwork spring unit constitutes by clockwork spring shell 1, clockwork spring 2 winders 3 that are arranged in the described clockwork spring shell 1, and the outer end of described clockwork spring 2 is connected mutually with clockwork spring shell 1, and the inner end of clockwork spring 2 and winder 3 are connected; The sidewall of described clockwork spring shell 1 is provided with axle sleeve 4; Described winder 3 cooperates with clockwork spring shell 1 sidewall spacers; Offer axis hole 5 on an end face of winder 3, winder 3 other ends extend in the axle sleeve 4 in this clockwork spring unit; Winder one end that offers axis hole 5 extends in the axle sleeve in the adjacent clockwork spring of the corresponding with it side unit, and its outer peripheral face passes through, and ratchet mechanism 6 is connected with this axle sleeve, and its axis hole is connected with the winder of this clockwork spring unit by ratchet mechanism 7; Ratchet mechanism 6 in the described axle sleeve is opposite with ratchet mechanism 7 clutch directions in the axis hole, and described many group clockwork spring whole units place in the dial sleeve 8, and clockwork spring shell 1 outer peripheral face in every group of clockwork spring unit passes through ratchet mechanism 9 respectively and is connected with described dial sleeve 8 inner peripheral surfaces; One end of dial sleeve 8 is provided with that the axle sleeve of dial axis 12 and first group of clockwork spring unit is suitable, and the other end is provided with terminal output shaft 34, and this terminal output shaft 34 is connected mutually with clockwork spring 2 in last group clockwork spring unit, and fixed drill bit 56.
